Thrust ball bearings Thrust ball bearings are separable bearings, according to their structure into two-way one-way thrust ball and thrust ball bearings. One-way thrust ball bearings can withstand axial load in one direction, two-way thrust ball bearings can withstand axial load in both directions. They all can not bear radial load. Thrust ball bearings are the structure with a seat, leaving it as the installation of seat spherical shape, it has a self-aligning bearing performance reduces installation errors. Thrust ball bearings are mainly used in automotive, machine tool industries.
