Both washers contain grooves for the balls. Thrust Ball bearings are of two types: single type which can support axial loads in only one direction and double type that can support bi-directional loads.
The central washer of double type thrust ball bearing is located in an axial direction by a shaft shoulder and sleeve. Thrust Ball bearings are not suitable for high-speed rotation since lubri~ant is expelled by centrifugal force.
When used on a horizontal shaft, a minimum axial load must be applied. Pressed steel plate, polyamide resin, machined high-strength brass or mild steel are used for cages. Care must be taken in handling to prevent damage to the separable rings and ball assembly.
