thin section bearing Thrust bearings thrust ball bearings and thrust into roller bearings

Thrust ball bearings and thrust ball bearings and thrust into angular contact ball bearings. Raceway washer by the band and the ball and cage components and the shaft with raceway ring called shaft washer, and the shell with raceway ring called seat bidirectional bearing and the shaft will be in the high precision bearings ring with one-way bearings can withstand axial load, two-way bearings can withstand axial load. appear before the installation of seat spherical bearings with aligning properties, can reduce installation impact of errors. such bearings are mainly used in automobile steering mechanism, the machine spindle.
Thrust into thrust cylindrical roller bearings roller bearings, spherical roller thrust bearings, thrust tapered roller bearings, thrust needle roller bearings.
Thrust cylindrical roller bearings are mainly used in oil drilling rig, made ​​of iron steel machinery.
Axial spherical roller bearings These bearings are reali slim bearings mainly used in hydroelectric power, vertical motors, marine propeller shaft, crane, extrusion machines.
Tapered Roller Bearings Thrust Bearing these main purposes: one way: crane hooks, swivels oil rig bidirectional: rolling mill roll neck.
Thrust bearing assembly mainly axial load, its wide application. Although the thrust bearing installation operation is relatively simple, but the actual repair is still often an error occurs, the tight and loose ring ring bearing mounting location that is incorrect, the results of the bearing out of action, the journal will soon be worn. Retaining ring mounted on the end face of the stationary member, the mounting error. Tight inner ring and the journal for transition fit to drive when the shaft is rotated tight ring, and the end surface friction with the stationary element, mobile crane bearing the axial force in the subject (Fx), it will appear larger than the inner diameter of the friction torque with the drag torque, resulting in tight ring and the shaft with face mandatory rotation, aggravated journal wear.
