  Thrust roller bearing

The thrust roller bearing is used to bear the combined axial and radial loads mainly including axial load, but the radial load shall not exceed 55% of the axial load. Compared with other thrust roller bearings, this kind of bearing has lower friction coefficient, higher rotating speed and self-aligning performance.
