K 81144 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 speed and self-aligning performance. Bearings are mainly used in heavy machine tools, high-power marine gearbox, oil drilling rig, vertical motor and other machinery.
