thrust ball bearings can only bear axial load

The thrust bearing is generally composed of two or more thrust washers thrust washers and several rolling body composition, generally divided into shaft thrust washer tablets and seat pieces , rolling is generally the most common type of iron or copper cage assembly into the overall quality of this type of bearing is the most common type thrust ball bearings.
Thrust ball bearing is a separate high precision bearing 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 mainly axial , radial joint load , but the radial load should not exceed 55% of the axial load . With other thrust roller bearings, such bearings lower friction coefficient , high speed, and aligning performance . 29000 -based non-stick Hydrodynamic Bearing bearing symmetrical 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.
