Types of Bearing Classifications and How They Work
Race. Ball bearings races fall generally into two designs: angular contact and radial. Angular contact bearings (image right) load the balls at angles to the perpendicular radial planes, whereas radial contact bearings (image above) load the balls through the perpendicular planes. Angular contact bearings are generally preferred where axial ...
What Are Roller Bearings? | Types and Applications
Browse All Bearings While roller bearings can handle higher loads than conventional ball bearings, their applications are generally limited to low-speed operations. Many types of roller bearings are self-aligning, and are easily able to overcome misalignment and mounting issues — cutting down on maintenance, repair, and labor needs.

Race (bearing) - Wikipedia
Each race is a ring with a groove where the balls rest. The groove is usually shaped so the ball is a slightly loose fit in the groove. Thus, in principle, the ball contacts each race at a single point. However, a load on an infinitely small point would cause infinitely high contact pressure. In practice, the ball deforms (flattens) slightly ...

Rolling-element bearing - Wikipedia
A rolling-element bearing, also known as a rolling bearing, is a bearing which carries a load by placing rolling elements (such as balls or rollers) between two bearing rings called races.The relative motion of the races causes the rolling elements to roll with very little rolling resistance and with little sliding.. One of the earliest and best-known rolling-element bearings are sets of logs ...
