STS Metal Bellows Couplings: High Quality Brand and Functionalities Combined

Blog | October 10th, 2019

Drive couplings are expected to provide adequate power transmission efficiency. Well, the word “expected” doesn’t really do this challenging operation justice. There can be no backlash, no shaft deviation, and no connection misalignment issues in evidence when two shafts are properly power-synced. A tough mandate to implement, engineers use the slight give-and-play built into bellows […]

The Differences Between Roller Bearings and Ball Bearings

Blog | September 17th, 2019

Different from ball bearings, cylindrically fashioned roller bearings are built to handle heavier loading effects. Basically, those tubular rolling elements are more capable of distributing force over a larger area. They can, therefore, process heavier rotating weights. Not to be outdone, since spheres curve equally in all directions, they’re better at tackling thrust forces. Equipped […]

The Effects of Lubricant Incompatibility to Bearing Life

Blog | September 2nd, 2019

Surely there’s already enough bearing fatiguing forces in play? Thrust forces pull at rolling elements while micro welds roughen point contact zones. Spalling races create noise and excessively high thermal envelopes while heavy loads threaten to crack stainless steel rollers. Making matters worse, lubricant incompatibility hardships can leach a bearing’s slippery properties. The oily stuff, […]

The Difference Between Anti-friction Bearings and Hydrodynamic Bearings

Blog | August 6th, 2019

Classed as rolling contact devices, anti-friction bearings operate on a well-recognized principle. Their rolling elements are in contact with one another. Set in motion, the lubricated rollers power along, and between, two rings while locked inside a caging mechanism. For hydrodynamic bearings, a whole other process is taking place. Instead of a group of solid […]

How Improper Mounting Can Cause Premature Bearing Failure

Blog | July 16th, 2019

Generally, the inner ring of a rotating bearing locks tightly against a shaft so that the two mechanical parts can spin as one. In order to accommodate this operation, massive amounts of pressure force a slightly smaller ring opening onto a slightly larger shaft circumference. That’s how press fit fastening works. Regrettably, this high-tolerance press […]

How Load-carrying Capacity Affects Bearing Service Life

Blog | July 1st, 2019

Rolling elements, just like human beings, are expected to handle stress. Now, people do succeed in dealing with such pressures, at least to some degree or other. For bearings, it’s a little harder. They can’t adapt, not easily. No, to properly deal with load-induced stress, their carrying capacity should be determined before they’re pressed into […]

Food-grade Bearings: Proper Material Selection for Health and Safety

Blog | June 17th, 2019

Here’s a tough mandate to solve. In an industrial setting, a set of bearings can be porous and packed with grease. Shifting this scenario so that the mountings are situated inside a food-grade equipment frame, those normally beneficial features assume application-deleterious proportions. The regulations protecting the equipment can’t permit just any old grease type, nor […]

Amplitude Demodulation for Condition Monitoring of Bearings

Blog | June 2nd, 2019

Far from straightforward, it’s not easy to track bearing damage. As one effective defect localizing solution, engineers use condition-based monitoring technology to monitor particular performance-biased subsets. Then, by applying some form of amplitude demodulation assessment, the condition monitoring techniques reveal behavioural information about a chosen bearing’s functions. Of some problem here, this is a mathematically […]

Common Causes and Remedies for Roller Bearing Overheating

Blog | May 15th, 2019

This post is intended as a guide to roller bearing overheating causes. One easy enough causative factor to spot would be a low lubrication level. There’s no oily film between the rollers, so the fast-moving bearing components generate heat as they rub against one another. It’s a pity that every overheating gremlin can’t be picked […]

What is Rolling Contact Fatigue in Bearings?

Blog | April 30th, 2019

Rolling point fatigue, as the term implies, occurs as a consequence of point contact stress. With these focal points rubbing together, material wear is inevitable. The hardness-to-malleability coefficient of the bearing alloy counteracts the effect, at least as much as is possible, but there comes a moment when those stress-focusing contact regions can no longer […]

Understanding What Limiting Speed of Bearings is All About

Blog | April 16th, 2019

Equipment shafts, they can only go so fast. Beyond that point, the rolling elements on each shaft end start to cook. It seems like the laws of physics have something to say about an out-of-control rotating bearing. Bound by those laws, a speed and its additional friction causes a subsequent increase in operational heat. Left […]

What are White Etching Cracks in Roller Bearings?

Blog | April 2nd, 2019

Appearing as pale hairline fissures, white etching marks emerge on bearing surfaces when application stress conditions exert heavy kinetic energies. The true material defect is hidden inside the alloy, so the etching cracks are the tip of the proverbial iceberg here. They’re a sign of a deeper issue. There are no two ways about it, […]

Common Solutions on How to Prevent Bearing Brinelling

Blog | March 18th, 2019

As detailed previously, bearing brinelling is an indentation effect that occurs when the elastic limits of a product’s race surfaces are surpassed. The balls push against the hard steel ring, and the spheroids create dents. Knowledge is power, as they say, so surely this particular nugget of information must be of help as a dent […]

Bearing Brinelling in Ball Bearings: What is it all about?

Blog | March 5th, 2019

Brinelling takes place on a bearing when its internal surfaces accumulate indentation damage. What causes the raceway dents? As with most mechanically caused problems, there are unmanageable mechanical stresses acting on the bearing parts and materials. A system overload smacks a rolling element hard, it deforms the raceway, and the brinelling effect amasses. Bearing contaminants […]

Significance of Bearings in the Performance of Idler Pulleys

Blog | February 26th, 2019

Idler pulleys are classed as non-drive rollers on a belt or chain impelled conveyor system. Now, without thinking about bearing features, we think about how unpowered idlers take up drivetrain slack. They enhance belt drive performance, in other words. But system idler pulleys feature another talent. Equipped with high-performance rolling elements, they work behind the […]

What are the Benefits of Linear Motion Bearings in Industrial Settings?

Blog | February 13th, 2019

Linear bearings, the term sounds somehow counterintuitive, are designed differently. The bearings don’t use the standard rings and races that most rolling elements inhabit. That’s because there’s no rotating shaft to support and isolate here, not in the following applications. No, rings are out, rods and sliding bars are in, and everything is new again. […]

How Do Ball Bearings Reduce Friction of Moving Parts?

Blog | January 29th, 2019

Ball bearings are what most folks think about when they imagine rolling elements. Sure, a proprietary roller type will handle a predetermined frictional load, but these elements aren’t exactly versatile. They’re built to satisfy specialized rotating applications. As for ball bearings, they can rotate in any direction, as directed by multiple loading forces. Ball Bearings […]

Understanding Speed Reducers and Their Purposes

Blog | October 23rd, 2018

Non-engineering types aren’t aware of basic system design issues. And that’s okay, they shouldn’t ever need to know about such things. Instead, they make blanket assumptions. One such assumption imagines a need for high rotational velocities at all times. Speed reducers, a common feature in power transmission linkages, suggest there are applications where lower velocities […]

Bearings Used for Conveyor Belts

Blog | October 9th, 2018

Conveyor bearings are specifically built to quietly facilitate linear belt motion. Arguably, they’re the central components in the system, so their mechanical characteristics are mirrored by a conveyor belt’s performance. Consequently, if these rolling elements interface efficiently between the equipment frame and the belt pulleys, then the product stream loaded on the belt will move […]

What Causes Bearing Noise?

Blog | September 12th, 2018

Among a cluster of synchronized, quietly rotating mechanical parts, one shaft is emitting a bone-rattling squealing noise. Off the top of the maintenance engineer’s head, the bearing is probably running dry. The lubricating film is breaking down. That’s a good guess, one that might even hit the mark, but that supposition can’t be confirmed until […]
