Thrust ball bearing application classification

Thrust ball bearing application classification

Thrust ball bearings are also divided into thrust ball bearings and thrust angle contact ball bearings. The raceway ring, composed of the washers with the raceway and the ball and the cage assembly, is called the shaft ring, the raceway ring with the housing is called the seat ring. The two-way bearing will be combined with the shaft. Bidirectional bearings can withstand bidirectional axial loads. The bearings with spherical surfaces of the mount surface of the seat ring have the cardiac properties that can reduce the impact of installation errors. These bearings are mainly used in automotive steering mechanisms, machine spindles.

Thrust roller bearings are divided into thrust cylindrical roller bearings, thrust tuned roller bearings, thrust conical roller bearings, and thrust roller bearings.

Thrust cylindrical roller bearings are mainly used in petroleum drilling rigs, iron - made steel machinery.

Thrust tuned roller bearings are mainly used in hydraulic generators, vertical electric motors, propeller shafts for ships, tower cranes, extruders, etc.

Thrust cone roller bearings such bearings main use: one-way: crane hook, oil drilling rig ring.

Plane thrust bearings are mainly subjected to axial loads in assemblies and are widely used. Although the thrust bearing installation operation is relatively simple, but the actual repair is still often errors, that is, the bearing tight ring and pine ring installation position is not correct, resulting in the bearing loss of action, shaft neck is quickly worn. The tight ring is mounted on the end face of the stationary piece, i.e. the wrong assembly. The inner ring of the tight ring and the shaft neck are in transition, when the shaft rotates, the tight ring is driven, and friction occurs with the end face of the stationary piece, when the friction altogether is greater than the resistance moment of the inner diameter, resulting in the forced rotation of the tight ring and shaft with the surface, aggravating the wear of the shaft neck.
