A thrust bearing is a rotary type of bearing.
composed of a "washer-like" bearing ring with raceway grooves for the balls
Like other rotary bearings they permit rotation between parts and are designed to support a high axial load .Thrust bearings are used in higher speed applications that require oil lubrication
thrust ball bearings come in two designs: single direction and double direction. The single direction design Consists of two rings,and double direction design, consists on three washers and two ball and cage assemblies
