Yrt Rotary Bearing

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 Yrt 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.

While there are dozens of variations of Yrt rotary bearings—including designs made for specific environments, mounting configurations, and applications—the most common categories are covered here.
