YRT Rotary bearings are common components in motion systems. They’re used in gearboxes, motors, pulleys, fans, pumps—virtually any time a shaft is rotating, rotary bearings are there to reduce friction and support radial or axial loads. The classification of rotary bearings begins with the type of bearing that supports the load—ball or roller. Within the ball and roller types, the next distinguishing feature is the primary load direction that the bearing can withstand—radial or axial (aka thrust). Then, ball bearings are further classified by the configuration of the outer ring, while roller bearings are further categorized by the shape of the rollers.

YRT Rotary bearings are categorized by whether they use balls or rollers, and then by the type of load they’re designed to support: radial or axial (thrust). Further classification for ball bearings is based on the configuration of the outer ring, whereas roller bearings are further classified by the shape of the rollers.
