Thrust ball bearing is a separate type bearings, shaft ring, seat ring and cage , ball component separation . Shaft ring is aligned with the axis of the ring , seat ring is compatible with the bearing hole ferrule , and the gap between the shaft ; thrust ball bearings can only bear axial load , one-way thrust ball bearings can only bear axial load in one direction , two-way thrust ball bearings can withstand axial load in both directions ; thrust ball bearings can not limit the radial displacement , low speed limits , one-way thrust ball bearings can limit the shaft and the housing of a direction of the axial displacement , two-way bearing can limit the axial displacement in both directions .Thrust roller bearings for axial load Rolling mill bearing mainly axial , radial joint load , but the radial load should not exceed 55% of the axial load . With other thrust roller bearings, such bearings roughness measuring instrument lower friction coefficient , high speed, and aligning performance . 29000 -based non-stick bearing symmetrical contact angle measurement spherical roller , can reduce the roller and the raceway at work relative sliding and roller length , diameter, roller quantity, high load capacity , usually oil lubrication, individual low speeds available greased . In the design selection , preference should be given ; 80000 Thrust cylindrical roller bearings, 90000 Thrust tapered roller bearings and thrust needle roller bearings AXK type , can withstand a one-way axial load, it is more than the axial thrust ball bearings load capacity is much greater, and rigidity, small axial space occupied . Thrust cylindrical roller bearings and thrust needle roller bearings for low speed applications , thrust tapered roller bearings speed slightly higher thrust cylindrical roller bearings.
In the design selection , preference should be given
