Does My Spindle Bearing Need to be Repaired or Replaced?

     
         

Bearings are incredibly important in our world. While most might not realize it, anyone in the industrial world knows better. Industrial machine tools used to cut, bend, shape, form, and fabricate many of the metal parts, components, and products we use frequently rely on effective bearings. As the years have passed, those machines have gotten more and more precise and powerful, leading to the spindle bearings inside the machines becoming more and more advanced as well.

However, gone are the days where a little bit of imperfection was acceptable. Today, precision and accuracy are key, and without effective spindle bearings, manufacturers can’t deliver it. If you ask any spindle provider or manufacturer what questions they might frequently hear from customers, it is likely that one of their responses will be something along the lines of: “Do my spindle bearings need to be replaced?” or “How will I know when I need new spindle bearings?”

Unfortunately in most cases, by the time a spindle bearing becomes the “squeaky wheel, begging for grease” chances are it already needs to be replaced. In the industrial sector, so many businesses rely on spindle bearings. Considering the fact that many manufacturers and fabricators operate around the clock to stay competitive and meet the demands of customers, it becomes apparent that spindle bearings are constantly being used and abused – almost without thought. That’s why it often comes as a surprise when productivity suddenly stops, and it all comes down to the spindle bearing. With this in mind, it’s incredibly important to not only keep spindle bearings properly lubricated and maintained, but to also be ready with replacement spindle bearings to eliminate costly downtime.

Whether they are for a mill, lathe, cutting tool, or anything in between, spindle bearings are absolutely necessary for the high level of power and precision that machine tools require. But how do you know when they need to be replaced? The most obvious sign is that the machine stops working. However, there are a number of other factors that come into play.
When you operate the machine tool in question, is precision or accuracy suffering? Noticeable changes in precision and positional accuracy can be indicative of an underlying problem with your bearing, the rolling element, the housing, or a number of bearing components. However, many times you will hear a failing spindle bearing before you notice the results. Are you hearing a low pitched grinding noise that becomes louder with faster rotation? As is the case with any machine, if it doesn’t sound right – chances are there’s a problem. The same is true for spindle bearings.

Beyond noticeably lower precision and audible signs of poor bearing performance, you might be able to assess the bearing visually. Are the bearings balls or rollers scored and rough? Is the bearing assembly damaged and worn? Whether your bearings have received a high degree of wear and tear from regular use or lack of lubrication, if you spot any of these signs, it’s possible that your bearings need to be replaced (or will need to be replaced very soon).

If your spindle bearings don’t need replacing, don’t forget to keep them lubricated and maintained to extend their life and increase your productivity.

The Bearings Behind Machine Tools

     
         

In every manufacturing facility in the world, you’ll find a bearing. Modern machinery, machine tools, and manufacturing equipment all rely on the movement and rotation that spindles deliver, and all of those spindles rely on bearings. At Eastern Industrial Automation, we frequently advise customers on the best spindle bearings for various applications. But if you aren’t quite initiated into the industrial world, please feel free to read on to learn more about spindle bearings and why they’re so important.

barden-spindle-bearing

Ball bearings, as the name implies, use a ball to carry the load. Because of the single point of contact created their load carrying capacity is slightly lower than roller bearings. However, ball bearings have the added benefit of being capable of carrying both radial and axial loads. The added benefit of this configuration is the ability to handle misalignment. With these factors in mind,they can sometimes be much cheaper than other solutions.
While still containing a rolling element, roller bearings are slightly different from ball bearings in the sense that instead of multiple balls aligned as the rolling element, multiple rollers are used instead. They typically have a higher load capacity than other varieties but they are not as adept at loads perpendicular to the rolling element. Rollers also tend to suffer more when misalignment is present. So these factors must be taken into consideration when you’re choosing a bearing for your own tools or equipment.

While ball bearing configurations tend to remain relatively simple, including the balls, the cage, and the raceway, roller bearings can take a number of different forms. Cylindrical rollers, for example, are one of the most common types. In terms of bearing designs in general, roller and cylindrical bearings are some of the oldest forms of rolling-element-bearing, and date back as far as 40BC. But time has treated the basic design very well.

Other varieties of roller bearings take advantage of various shapes and forms of rolling element. For instance, while most roller bearings take only radial or axial loads, the tapered roller bearing uses conical rollers to provide the heavy load capacity of other roller bearings with the added benefit of being able to carry both radial and axial loads. However, this benefit comes with its own slew of caveats. Because of the conical shape of tapered roller bearings, added friction can often result with heavy loads due to the tendency of the conical roller to act like a wedge. On the other hand, spherical roller bearings take advantage of an outer ring with a spherical shape. This allows the spherical roller to effectively handle misalignment, while sacrificing the reduced friction achieved by other rolling element bearings. For every advantage of a bearing design, there is a disadvantage. And every design addresses a specific set of requirements many business demand for their machines. In any case, the challenge for many is finding the right features for their specific machines.

But what are all of these bearings used for? They’re in your chair, your desk drawer, and your computer. But one of the areas they matter the most is in the industrial world as machine tool and spindle bearings. One of the most common uses for bearings is in machine tools. For the many types of industrial equipment that rely on spindles, bearings ensure the precision that businesses rely on every day to stay productive, efficient, and profitable. Whether that means ball bearings or rolling element bearings, in every case – the spindle bearings in industrial equipment make a major difference. Just like bearings come in a number of varieties, spindle bearings range from the simplest ball bearings and roller bearings to highly advanced hybrid solutions needed when extreme precision and power are at play, striking a fine balance that dances between load capacity and longevity.
Regardless of the application, spindle bearings continue to dictate the level of precision many businesses are capable of. With businesses operating around the clock to manufacture the tools, equipment, and commodities we rely on – they need spindle bearings that have been engineered to last. Luckily, bearing manufacturers around the world have answered the call with solutions that have consistently gotten more and more effective and reliable.

How have you benefited from a spindle bearing today?

The Vital Role of Spindle Bearings and Proper Upkeep

     
         

Chances are, everyone you’ve encountered today has somehow relied on a spindle bearing. If you’re reading this, you probably knowingly use spindles and spindle bearings on a frequent basis. However, it is easy to forget how vital proper reconditioning and upkeep are.

skf-spindle-bearings

Bearings and machine tools are so ubiquitous in the manufacturing and industrial world that we sometimes tend to take them for granted. Too often this is the case, and spindle bearings chug along unnoticed until they demand attention by causing a problem. After all, the squeaky wheel gets the grease, right?

While it’s true that most spindles and bearings can technically operate day after day after day, it would require proper lubrication and handling as well as operation under ideal conditions. Whether it means the potential for contamination or prolonged usage under heavy loads, conditions are almost never ideal. At the same time, operation, installation, and maintenance can also often be less-than-perfect.

With that said, preventative maintenance can help manufacturers ensure that they get the absolute most out of their equipment, while also helping them avoid more costly repairs further down the road.

Maybe the harsh economy has forced manufacturers to get more proactive about staying cost efficient, but regardless of the underlying cause, remanufacturing and reconditioning spindle bearings and machine tools has become very popular.

The main benefits of reconditioning spindle bearings are simple: more accurate spindle bearings that last longer. However, it goes far deeper than that. Remanufacturing and reconditioning your spindle bearings are both extremely cost effective methods for damaged or worn bearings. At the same time, this also provides more up-time, instead of waiting for a replacement bearing.

But how might you (or a professional bearing provider) go about reconditioning a bearing? First, the bearing is disassembled and cleaned. Next it is thoroughly checked both visually and microscopically, before ring hardness and dimensions are tested. Next, the extent of reconditioning necessary is established, ranging from simple buffing or polishing to component replacements.

Many times, reconditioning is even done to improve the bearing beyond its properties and surface finish when it was new. This is often accomplished through grinding and polishing of the bearing, its sides, the I.D, O.D., and all of its surfaces.  Typically, to finish the reconditioning, cages are inspected for damage and new rolling elements are installed.

Cost efficiency has never been more vital for manufacturers around the world. While this brief outline doesn’t do justice to the depth and scrutiny of the reconditioning process for spindle bearings, it hopefully underscores the importance of active and scheduled preventative maintenance as an extremely powerful way to improve efficiency.

How Reduced Friction Improves Spindle Bearings & Your Business

     
         

At Eastern Industrial Automation, we frequently provide customers from a number of industries with the spindle bearings they need to stay productive.

If you consider yourself a part of the industrial sector, chances are you know what a spindle is. When it comes down to it, all a spindle really is, is the rotating axis of a machine and everything that goes along with it. Many times, the spindle bearings and everything attached to the spindle gets bundled into this definition, but it’s important to remember how critically important effective spindle bearings are for both the life of the machine, its performance, its efficiency, and the productivity of any business that relies on it. However, when you consider what makes a spindle bearing effective, it tends to come down to friction. From lowering costs to increasing quality – the lower the friction, the better.

First, we’ll look at what makes spindle bearings different. As you’re well aware, low friction is one of the most important concerns when it comes to good spindle performance. Many rolling bearings boast low-friction these days, and they’re not lying. However, some of the newer technologies have given spindle bearings the chance to deliver an entirely new level of performance. One of the primary advances in spindle bearing technology is the introduction of the hybrid spindle bearing, which takes advantage of steel rings and ceramic balls. This variation of the spindle bearing represents a major performance improvement for machine tool spindles.

For example, more advanced spindle bearings (like hybrid bearings) tend to last up to six times longer than conventional spindle bearings. On top of fewer lubrication and vibration problems and extremely high speeds, hybrid spindle bearings also make it possible to speed-up and slow-down the bearing much faster than other standard high-speed bearings. For the most part, all of these benefits boil down to an almost unbeatable reduction in friction.

In many businesses, the lower friction of hybrid has allowed for noticeable increases in speed when compared to standard all-steel bearings. However, they have also helped businesses drastically lower operating costs while increasing production quality.

Due to the smoother surface, smaller contact area, and lower thermal expansion of ceramic, hybrid bearings don’t just deliver better performance – they also allow save money. While many industrial businesses rely on expensive specialty formulated lubricants to keep their all steel bearings running smoothly, hybrid bearings demand far less. In fact, the demands placed on lubrication by hybrid bearings are so small that many businesses around the world have been able to replace their expensive grease lubricants with low cost alternatives. But it doesn’t stop there. Due to the basic properties of ceramic, hybrid bearings are capable of withstanding wider operating speed ranges and greater resistance to poor lubrication, making them last far longer than all-steel bearings. Combine all of this with the fact that reducing friction also reduces power-loss, and you have a spindle bearing that helps business perform better and save more in virtually every way possible. However, these advanced spindle bearings don’t just save money.

When it comes to spindles, stiffness plays a very important role when it comes to the quality of the product being machined. When the bearings are stiff, so is the spindle. To make the conditions right for a stiff spindle, the bearings must be preloaded. However, a certain degree of thermal expansion I caused in all-steel bearings when machines heat up. Ceramic bearings are much less sensitive to this, which helps maintain a more effective preload, a stiffer spindle, and – ultimately – a better product.

The Advantages of Pneumatics

     
         

At Eastern Industrial Automation, we provide pneumatic solutions for customers across the country and from a wide variety of industries. Regardless of your business, if you rely on pneumatics — we have the solution here. However, if you just want to know a little more about pneumatic systems and how the technology has progressed, you’ve come to the right place.

Pneumatic technology is a term that referrers to the use of pressurized gas to produce mechanical motion. This technology is used in many industrial settings. These industrial factories are plumbed with compressed air or inert gases. Next we take a look at the primary advantages associated with pneumatic technology.

The air that is actually used inside these pneumatic devices is dried. When the air is dry it is free from moisture. When there is no moisture within the air it cannot create a problem to the internal parts within the system. Also oil or other lubricants are added so the effects of friction can be minimized. With most of the devices being air based they are relatively simple in design and require inexpensive material to function. As a result mass production can be input to create pneumatic systems. This method will save you a significant amount of time and money.

Significant technical advantages have kept pneumatic instruments relevant in the ever changing industrial climate. One significant advantage is the overall safety that can still be found in pneumatic field instruments. This advantage revolves around pneumatics ability to operate without the use of electricity. Without electricity the hazard of electrical sparks cannot be generated. With no sparks your industrial environments risk of potential fires or explosions is reduced dramatically. In addition some specialized pneumatic instruments can operate in high-temperature and high-radiation industrial environments. This is an advantage because most electronic instruments would not be able to operate in these environments without rework to harden them. Although you can harden electronic instruments, it is more economic to use pneumatic instruments because they are immune to these environments by default.

Another key feature of pneumatic systems is their unique ability to continue to operate under a power failure. This is possible due to containers that store compacted air for the specific purpose of motor failure. Even if the motor does not operate the machine can still function using this stored compressed air. Also if for what ever reason a tube or valve leaks it will not pose a health or fire risk.

Compared to hydraulic equipment pneumatic equipment has a cost advantage due to the fact that hydraulic equipment will cost you twice as much as their pneumatic counterparts. Also when you compare the costs on installing a pneumatic water automation system with a convention electrical installation the cost savings by using pneumatics are significant. Closing and opening values work well with pneumatic systems due to its ability to sustain overload pressure conditions. In addition pneumatic actuators also posses an extended life and will function with little maintenance throughout the lifetime of the actuator.

The Importance of Food Grade Lubricants and how they keep us safe

     
         
lubrication

Kluber Lubrication products are one of our most popular products, offering a number of solutions for industrial lubrication.

Sometimes it’s easy to forget how vital proper lubrication is for your machinery. We often think of machinery is extremely dirty and grimy. However, when it comes to some industries — cleanliness is key, and that’s why food grade lubrication is a product we constantly stock for our customers.  While this is just one facet of industrial lubrication, click here to see the many lubrication products we offer.

When it comes to industrial lubrication, it can often be the difference between premature machinery failure and an effective operating machine. In the world of industrial lubrication not all lubricants are created equal. Automotive bearing lubricants and industrial application lubricants vary. One of the most important and unique variations of lubrications comes in the form of food grade lubricants.

When packaging or handling food the potential of grease and oil leaks would cause a concern if traditional lubricants were used. With food grade lubricants, over lubrication, a spill during maintenance or a leak will not compromise the food or beverage product. Food, beverage and pharmaceutical companies should continually implement the highest quality non toxic food grade lubricants to ensure the safety of their products for consumers.

Challenges constantly face lubricant marketers, equipment designers and lubricant formulation engineers as they strive to keep consumers safe in case of an accidental contamination. Lubricants used in the food processing industry have strict requirements and performance expectations that are understandably stricter than your normal industrial lubricants. There are currently three categories of food grade lubricants, these categories are broken down into H1, H2 and H3 lubricants.

These food grade designations categories were originally created by the United States Department of Agriculture. The H1 category of food lubricants focuses on food-processing environments where an incidental food contamination is possible. The H2 category focuses on food grade lubricants that are used specifically on equipment and machine related parts in areas where the possibility of contact is limited. The final category is the H3 category which is associated with food grade lubricants that are edible oils. These oils are used to prevent corrosion on trolleys, hooks and similar equipment.

If you still are not convinced of the importance of food grade lubricants here are some stories of how neglecting to use the proper lubricants can come back to hurt you. In 1998 Smithfield Foods recalled 490,000 pounds of smoked boneless hams due to contamination. The food was contaminated by non food grade gear lube and was reported when customers started reporting a foul taste and a burning in the throat from eating the contaminated ham. Another case occurred in 2000 when 86,000 pounds of deli meats were recalled due to non food grade lubrication contamination. These consumers reported an odd odor and flavor in the meat. A few people also said they experienced temporary intestinal problems. After citing these accidents you can see the importance of using food grade lubricants to protect your products and company image.

Spindle Bearings and the Rotation Our World Relies On

     
         

At Eastern Industrial Automation, we know know machines. We also know that your business needs reliable spindle bearings to stay productive. Whether you’re just doing the buying or would like to know a little bit more about spindle bearings, read on. Or, check out our selection of spindle bearings here. spindle-bearings

Think about the amount of devices, machines, and tools that rely on rotation. Drills for instance are a tool that you benefit from far more than you may realize. However, you also rely on the components of that drill. With that in mind, if it wasn’t for years upon years of innovation taking place in the industrial sector, many tools – both the ones that are handheld and the ones that occupy entire rooms – wouldn’t be able to provide you with the products and daily necessities that you count on.

One of these essential components is the spindle, the rotating axis of just about any machine that moves. Ever since the industrial revolution (and before) spindles have been essential when it comes to the machines that produce everything from broom handles to more machines. From the simplest machine to complex metalworking equipment, the impact of the spindle can be seen in just about any setting, however inside every one of them you’ll find bearings. Without years upon years of innovation in terms of spindle bearings and their technology, our world might be very different.

From high tech lubrications that have been developed to the actual design and manufacturing, spindle bearings have come a long way (as have bearings in general). As bearings go, some of the first bearings were wooden ball bearings found in the remnants of ancient Roman Ships. Back then, they were used in rotating tables, and friction was a common problem. To address the problem of friction, many of the innovations brought to bearings to this day have addressed that very problem.

When it comes to machine tools, friction is typically one of the biggest concerns due to the high speed nature of machine tools. The machine has to be able to provide high speed rotation for a cutting tool like a drill, while reducing friction. To accomplish this, the most common type of bearing used in spindles tends to be the angular contact bearings, which provide high speeds, high load carrying capacities, and high precision. Considering that many of these machine tools are used to cut metal, these properties are absolutely essential.

Many times, angular contact bearings are used where a light to moderate load is needed for cutting applications. When spindle bearings need to withstand a heavier load, tapered roller bearings are used for their greater load-bearing ability. In any case, the technology to provide these bearings has continually been expanded upon for years. From Friedrich Fischer, who perfected the shape, size, and roundness of ball bearings to the implementation of materials like Teflon, ceramics, and synthetic balls – innovation has continually expanded the capabilities of spindle bearings – which has in turn expanded the capabilities of the machines that rely on them.

Keep your machines running with effective grease and oil seals

     
         

Here at Eastern Industrial Automation, part of our passion is in keeping your machines running smoothly, efficiently, and effectively. A large part of that is ensuring you have the right grease and oil seals for the job. From dirt and debris to harmful contaminants, grease seals and oil seals To learn a bit about the seals behind your machines, keep reading.

Whenever something is running smoothly and the introduction one thing somehow brings everything to a screeching halt, you’ll often hear the idiom that goes something along the lines of, “Well he sure threw a wrench in the works there, didn’t he?” This saying can be applied to a lot of contexts, but when it comes to the world of machinery and industrial automation – it says a lot. In reality, a lot can “throw a wrench” into a system, whether the system you’re referring to is an automated assembly line or a machine tool. To prevent this metaphorical “wrench throwing” in the industrial world, a number of manufacturers have dedicated themselves to designing, manufacturing, and perfecting the one thing used around the world to keep mechanical systems running smoothly: oil seals and grease seals.
In many cases, mechanical systems tend to be relatively closed systems, meaning that they are not always designed to exchange materials with the “outside”. Dirt, fluids, dust, and other forms of ingress can negatively affect even the largest machine. In the same way, and especially for machines, keeping certain materials and substances like lubrication in can be just as important as keeping other materials out. So when it comes to industrial automation and machine tools – regardless of size –  the business of keeping closed systems closed has become a big one. Without the many mechanical systems we rely on both knowingly and unknowingly, our lives would be very different. To keep these systems running smoothly, grease and oil seals have received continued innovation to help make machines more and more effective. This innovation can be seen in both the materials used to the way they are designed and manufactured.

The fact that grease and oil seals are an essential component in machinery, and have been for many years, is very real. In the very early years of the automotive industry grease and oil seals were no less essential than they are today, but manufacturers and mechanics had to rely on more rudimentary seals than what we have access to today. For instance, most of the seals were made out of leather – and some of the seals produced in the very early days of the automobile were even made out of rope. While these seals were successful for the most part, it was largely because the wheels on those vehicles didn’t move as fast as they do today. More speed required a more effective solution. So as the cars rolling off the assembly line began to evolve, their components did as well. This naturally meant more efficient and effective grease and oil seals.

Eventually, the need for innovation lead to the first rubber grease and oil seals combined with a metal body for support. These seals proved much more effective, and gave the automotive industry some of the reliability and performance it needed to continue making cars more powerful. While automobiles are only one machine that need grease and oil seals, the side-by-side evolution of automobiles and the seals used inside them provide an ideal glimpse into how essential such a tiny component can be.  Today, many oil and grease seals from most major manufacturers feature a number of sealing designs matched to accommodate the various needs of original equipment manufacturers and aftermarket applications in the automotive, manufacturing, power transmission, and industrial sectors.

In every case, the design and innovation of oil and grease seals continues to enhance their ability to help many machines meet the demanding performance requirements we’ve come to expect.

From closing spaces components and preventing harmful contaminants from “throwing a wrench” into a closed system, to keeping lubrication confined where it’s supposed to be – seals are essential. For those not in the industrial world, this is a relatively simple matter. For the rest of us, it’s very clear that oil seals can mean the difference between success and failure for just about any type of machine or vehicle in operation everywhere, especially when it comes to high precision and close-fitting bearing systems.

If you need oil seals or grease seals for your applications, we have plenty. Check out our selection here.

The History of the Bearing, and Why It Matters for Your Business

     
         
fag-bearings

An example of a modern day bearing, manufactured by FAG Bearings

Here at Eastern Industrial Automation, we deal with bearings every day. Sometimes, it’s nice to look at where all of the technology came from. Recently, we looked into the history of innovation behind the bearings that pass through our many locations and we were a bit surprised by what we found. You might be surprised to learn that the bearings you constantly rely on were also pivotal for historic figures like Alexander the great, the Ancient Romans, and even Leonardo Divinci. All of the innovations by various civilizations continue to influence us today. For example, many of our customers take advantage of FAG bearings, which directly benefit from a long process of innovation that began many many years ago. To learn more about this history, and if you have a couple minutes to spare, read on.

Ball bearings are now a familiar component in tools, machines, and vehicles around the world. In a sense, their evolution can be directly linked with the growth of industry, automation, and machinery in general.  When it comes to the history of the bearing, leading businesses and industries around the world have taken advantage of the lesson history has taught us, to embrace innovation. In doing so they’ve created machines that are capable of more than previous generations would have ever thought possible. But where did it all start? While it wasn’t until the 19th century that innovators like Friedrich Fischer (founder of FAG) and Henry Timken (Founder of Timken) would make ball bearings suitable for widespread use in the industrial world, the clear benefit of rolling over sliding – evidenced by ball bearings everywhere – has been obvious since the creation of the wheel.

Innovation over hundreds of years has turned bearings into the necessity they are today, while making the machines that rely on them more effective. If the history of bearings can teach any business or industry a lesson, it’s that the machine is only as effective as its components. Without the bearing’s gradual progression, industry (and the world) as we know it would be very different.
Even with very little hard evidence from history that logs  and stones were used as early roller bearings, the development from sliding to rolling  undoubtedly began with the earliest civilizations. So if there is to be any clear beginning for the story of bearings as we know them today, it was there – before history even began.

While bearing design has changed a lot over the years, the physics that dictate how your bearings behave have not. This is precisely why clear evidence has been found from early roller and ball bearings used by Romans, Greeks, Chinese, and the Celts.

Aristotle was one of the very first recorded thinkers to make the observation that round objects receive much less friction than anything else. While this observation still didn’t give “birth” to the ball bearing industry, it did contribute to early battering rams used by Alexander the great, which relied on an early form of linear roller bearings. However, It wasn’t until 1930, when Italian Archaeologists uncovered a pair of Roman ships in Lake Nemi, that a clear example of early bearings was discovered.

An example of an ancient roller bearing, that might have been used by the Roman's on Nemi, or in one of Da Vinci's early design schematics.

Some of the items found in Lake Nemi were clearly the forerunners to modern bearings, including a fascinating ball thrust bearing used in what appears to historians and archaeologists to be a revolving platform, or table. While some ships had been discovered that used wooden balls for this purpose, the ships found in Lake Nemi used bronze balls, secured by iron strips to a fragment of wood. When compared to modern ball thrust bearings, the similarity is unmistakable.  When it comes to exploring the history of bearings, findings like this prove that the components we constantly rely on today are in fact a piece of ancient history that performed a similar role for our ancestors. The fact remains, however, that without advancing the science of bearings, similar advances in shipbuilding and industry wouldn’t have been possible.

If we fast forward to the Renaissance and Leonardi Da Vinci, we can continue to see the beginning of many of the ideas that impact our industry and our businesses even today.  While the bearings found in ancient Roman ships and Greek war machines were rudimentary at best, Da Vinci took the physics one step further and created some of the first caged bearings. In one of his iconic illustrations, Da Vinci sketched not only his concept of a bearing, but included in his sketch the essential component we take advantage of today – the retainer, or separator, to increase the efficiency and longevity of the rolling element.

With Da Vinci’s experimentation, a growing interest in bearings began to take hold with an even greater interest in reducing friction and wear, which – as any industry insider knows – continues to receive a great deal of attention today.

Today the concentration by many bearing manufacturers remains with endurance and longevity –where Leonardo Da Vinci left off. While the physics that govern motion won’t change, the task of reducing friction created by the bearing continues to bring innovation to the field – from incorporating new and exciting materials to using advanced lubrications. If anything can be learned by history it’s that machinists and manufacturers can’t afford to remain stagnant. The technology is here to improve performance and continue the progression that the earliest civilizations began.

Air Regulators: Making an Impact Every Day

     
         

Chances are you might not know what an air regulator is, but air regulators have a much greater impact on your life than you may know. Every day you benefit from pneumatic systems in direct and indirect ways, and air regulators are one component that help to make it all happen.

Pneumatic systems used everywhere utilize pressured air to make manufacturing, moving products, and automating processes significantly easier. For example, when a construction company is hired to fix the road you drive on – many times one of the tools they use are jackhammers. Or for a different example, consider the electronics you use every day. Chances are, when they were being created the manufacturer took advantage of tools like pneumatic grippers and vacuums to quickly, safely, and efficiently move various parts and components. In both cases, pneumatic equipment allow the job to be completed faster and with significantly more ease.

One component that makes this ease possible is the air regulator. For a pneumatic system, fast and reliable movement is imperative. So naturally, high quality pressure regulators are also needed to ensure consistent performance that can be depended on by all sorts of industries.

HOW DO AIR AND PRESSURE REGULATORS WORK

Much like a pressure regulator for water pressure works, an air pressure is, essentially, a valve that decreases or increases the air pressure by re-directing the air current. Naturally, the level of technology that has goes into this has continually developed into something that allows all kinds of innovation, but in any application pneumatic systems are capable of constantly monitoring pressure while fine tuning air regulators to extremely precise parameters.

WHY ARE AIR REGULATORS SO IMPORTANT?

Because the air regulator’s main function is to control the airflow through a pneumatic system, its job is absolutely critical. For instance, too much or too little pressure could mean the difference between breaking and dropping a part in a manufacturing setting. With this in mind, an air regulator working properly will increase or decrease the pressure as needed.

When pressure is released from the system, the air regulator is opened slightly, harmlessly releasing the pressure into the air. This safely lessens the pressure exerted on the pneumatic system and ensures proper operation while also making the system more efficient. At the same time, effective air regulation also reduces the strain on the rest of the components. That said, choosing the right air regulators for your application can make a significant difference when it comes to overall performance and efficiency.

THE BIRTH OF THE MODERN AIR REGULATOR

The most typical air regulator is a simple external handle that can be turned to close or open the valve and lessen the pressure. However, as the need for more precise pressure increases and decreases evolved in the manufacturing and medical industries, more advanced air regulators with digital interfaces made fine tuned adjustments possible.
