Thrust cylindrical roller bearing is composed of washer-shaped raceway ring (shaft washer, seat washer), cylindrical roller and cage assembly. Cylindrical rollers are processed with convex surfaces, so the pressure distribution between the rollers and the raceway surface is even. This kind of bearing is a separate structure, which can be installed separately for the shaft ring, seat ring, and rolling element components. It is not allowed to tilt the axis of the shaft and the housing during installation. It is used at low speed and can withstand one-way axial load without restricting the radial direction. Displacement. The axial load capacity is large, and the axial rigidity is also strong.
