Rotary bearings: Summary of types and variations for motion …

14/3/2018· 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 classifiion of rotary bearings begins with the type of bearing that supports the load—ball or roller.
