There is a vast array of bearing types and sizes for a good reason: every application has unique needs and specifications, and it’s important to use the right bearings for the job. When you work with a trusted bearing provider, you’ll have a large inventory of roller bearings, ball bearings, contact bearings, and more to choose from, and you’ll have the opportunity to create custom solutions. Your provider should be able to source and distribute your bearings quickly and efficiently, help you make decisions, and offer you the same standard bearing at various price points depending on where it’s being sourced from.

A rolling bearing is composed of: two rings – known as the inner and outer race – separated by a set of rolling elements, which are most often kept at a relative distance by a cage. At its most basic level a rolling bearing decreases rotational friction and supports radial and axial loads. Each element is manufactured to a certain tolerance, and the sum of the geometrical and form tolerances determines, loosely speaking, the level of performance of the bearing – rating the load it can carry axially and/or radially, the limiting speed, noise, etc.
