20.000 Millimeter (mm) Outer Diameter (D), 3,855 Newton (N) Dynamic Load Rating (Cr), and 3,571 Newton (N) Static Load Rating (Cor) Ball Thrust Bearing

A ball thrust bearing is a particular type of rotary ball bearing. Like other ball bearings, they permit rotation between parts, but they are designed to support a high axial load while doing this (parallel to the shaft). Higher speed applications require oil lubrication. Generally, they are composed of two washers, which may be either flat or grooved (with raceways), and the rolling ball elements are typically caged. As opposed to roller thrust bearings, ball thrust bearings can generally operate at higher speeds but at comparatively lower applied loads.
