​Bearings-General bearings-Thrust ball bearings
​F/FM

Thrust ball bearings are suitable for the accommodation of axial loads in one direction (single direction type) or two directions (double direction type) and consequently can locate a shaft in one or two direction(s). They may not be subjected to any radial load. The bearings are separable and mounting is simple as the components can be mounted individually.

Series of 51100 / 51200 / 51300 / 51400 / 53200 / 53300 / 53400 are most commonly used. F and FM series are also available for miniature and small sizes.
Double direction: Series of 52200 / 52300 / 52400 are most commonly used.
