Thrust ball bearings are divided into single and double direction types. The former is able to accommodate axial load in one direction, while the latter is able to accommodate it in both directions.

Neither is suitable for applications that involve radial load or high-speed rotation.

Bearings whose housing washer back face is spherical (with a spherical back face or aligning seat washer) are designed with a self-aligning capability and can accommodate the effects of inaccurate mounting.
