Heavy Duty 81208 M Axial Thrust Cylindrical Roller Bearing 81208M 40*68*19mm

Thrust roller bearings are used to withstand axial and radial combined loads, but the radial load shall not exceed 55% of the axial load. It is a separable bearing that can only withstand unidirectional axial load and slight impact, and can limit the axial displacement of the shaft (or shell) in one direction, so it can be used for unidirectional axial positioning. When rolling, due to the different linear speeds at both ends of the roller, sliding of the roller on the ring raceway is inevitable. Therefore, the limit speed of this type of bearing is lower than that of thrust ball bearings, and it is usually only suitable for low-speed operation situations. Mainly used in heavy-duty machine tools, high-power marine gearboxes, oil drilling rigs, vertical motors and other machinery
