Thrust Bearings
A thrust bearing is a particular type of rotary bearing. Like other rotary bearings they permit rotation between parts, but they are designed to support a high axial load while doing this (parallel to the shaft). Different kinds of thrust ball bearings are used to support different amounts of axial load. Thrust ball bearings are used in applications that use little axial load, where a ring supports ball bearings. Spherical roller thrust bearings are used in applications that require high axial load, and can also support shafts that are out of alignment. Thrust bearings are used in higher speed applications that require oil lubrication, such as in the automotive and aerospace industries. Generally, thrust bearings are composed of two washers (raceways) in which those for ball bearings may be grooved, and the rolling elements.
