Thrust roller bearing
|
89424 M thrust roller bearing is used to bear the combined axial and radial load dominated by 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. Thrust cylindrical roller bearings are mainly used in heavy machine tools, high-power marine gear boxes, oil rigs, vertical motors and other machinery.
