(1). Flat-race thrust bearings:

Consist of a pair of flat washers separated by the ball complement and a shaft-piloted retainer, so load capacity is limited. Contact stresses are high and torque resistance is low. The prime advantage of flat-race thrust bearings is they permit eccentricities, because there are no grooves to restrain one race from wandering slightly with respect to the other.

(2). One-directional, grooved-race thrust bearings:

It have grooved races very similar to those in radial bearings. Thrust bearing capacity is about twice that of the flat-race bearing and limiting speed is about three times as high. However, a thrust bearing has a limiting speed, which is still quite low because balls spin at high speeds.

(3). Two-directional, grooved-race thrust bearings:

It consist of two stationary races, one rotating race, and two ball complements. Thrust bearing characteristics are identical to those of the one-directional bearing, except thrust bearings can support thrust in both directions.
