Thrust Bearing

Thrust bearings are a particular type of rotary bearing that allow rotation between parts used but they are designed to support axial loads like vertical shafts for which spherical, conical or cylindrical rollers are used. They are used in gear sets like in car transmissions between gears and between the housing and the rotating shafts.

Thrust bearings are of different varieties. Ball thrust bearings are composed of ball bearings supported in a ring. They are used in low thrust applications where the radial load is very small. Thrust roller bearings are made of small tapered rollers arranged so that their axes converge at a point on the axis of the bearing.
