How Do Miniature Bearings Compare?

Posted by Bradley Irwin on September 23, 2016

Miniature ball bearings, also commonly known as Instrument bearings, play a role in an extensive range of applications.

In general, bearings are in the types of devices that allow for specific parts to move in relation to each other in a controlled fashion. The motion can be in rotation or linear. One prominent type of bearing is roller bearing.

Roller Bearings

The more well known rolling variety of bearing would be the ball bearing. These ball bearings are effective in reducing the friction that occurs between moving parts. In addition, there is a degree of elasticity in the ball that allows it to move and support different bearing loads.

Balls in these bearings are available in various sizes from large to the miniature versions. The smaller models, such as the miniature bearings, are useful in applications where there are limitations on space such as medical, electrical, and automotive devices.

Ideal for high-performance and compact designs, these miniature ball-bearings perform at extremely high speeds, along with low friction. Fortunately they also have very little service requirements.

These bearing types are durable and are able to handle light to moderate thrust and radial loads. They operate quietly and come in a variety of designs and types. Some of the types include stainless steel that come with shields or seals, along with a variety of lubricant options.

Ball bearings are described as machined components which include an inner ring, outer ring, retainers, snap rings, shields, and balls. The miniature versions are typically available in metric and inch sizes, unflanged, flanged, shielded, or open.


As with all bearings, the correct lubrication is extremely important to ensure the life and optimal operation of  miniature bearings. Today there are numerous common types of lubricants along with hundreds of the specialty type lubricants that are specifically formulated in order to match up with the demands and design requirements of different applications.

The extensive range of greases and oils serve the purpose of lubricating the contact that occurs between the bearing components, offer a barrier against contaminants or contamination, protect the surfaces of a bearing or bearings from corrosion, and, in some instances, also carry heat away.

The rolling-contact surfaces of these miniature bearings are constructed out of types of alloy steel to geometries and tolerances that are close to 1 millionth of an inch. General damage and wear caused from contamination, heat, corrosion, or sliding contact accelerates how quickly the lubrication reduces, which results in decreasing the life span of the bearing significantly.

The Importance of Clutch Release Bearings

Posted by Bradley Irwin on September 16, 2016

Anyone who can drive a manual transmission vehicle knows that they need to push the clutch to select a gear, and then release it while applying power in order for the car to move.

Once you’re familiar with the process, you don’t even think about it – it becomes muscle memory, and you do it automatically.

Beneath this simple behavior, however, there’s a bit more going on – an intricate mechanical system which makes sure your car shifts gears properly.

Understanding the ABEC Scale for Ball Bearing Ratings

Posted by Bradley Irwin on September 9, 2016

Every industry has its own standards that help individuals who are both in and outside of the business to understand the quality controls that are in place.

Even for something made out of hard metal like ball bearings, they have various degrees of strength and can handle different levels of pressure. Depending on what exactly is needed, different types of ball bearings might work or might not.

Replacing Trailer Wheel Bearings

Posted by Bradley Irwin on September 2, 2016

Monitoring your trailer wheel bearings is critical to the safe functioning of your trailer. If they are making noises, it might be time to swap out those bearings for new ones before you get stuck somewhere.

Here’s a quick video showing you how to do it…

For best success in this endeavor, you will need:

  • basic mechanical tools
  • solvent
  • hammer
  • punch
  • new cotter pin
  • new seals
  • new dust cups
  • new bearings
  • grease
  • support stands
  • flat surface to work on

If you prefer a written guide, refer to this old blog post, How to Change Trailer Wheel Bearings.

A Look At Greaseless Bearings

Posted by Bradley Irwin on August 19, 2016

Ball bearings are used almost everywhere, including in your car, bike, skateboards, and all other machines that have moving parts.

These devices have been around for centuries now. Ball bearings use the magic of physics to reduce friction among two metal parts in a machine.

Throughout history, the design of the ball bearing has remained almost unchanged. But the latest technology allows them to last longer and spin better. All this is without grease.

Welcome to the greaseless bearings…
