A: Thrust bearings are divided into thrust ball bearings and thrust roller bearings. Thrust ball bearings are divided into thrust ball bearings and thrust angular contact ball bearings. The raceway ring matched with the shaft is composed of a washer with a raceway and a ball and a cage assembly, which is called a shaft ring, and the raceway ring that cooperates with the housing is called a seat ring. 

A two-way bearing matches the middle ring with the shaft. One-way bearing It can bear the one-way axial load and two-way bearing can bear two-way axial load. The bearing with the spherical mounting surface of the seat ring has self-aligning performance, which can reduce the influence of installation error. Such bearings are mainly used in automobile steering mechanisms and machine tool spindles.

Thrust roller bearings are divided into thrust cylindrical roller bearings, thrust spherical roller bearings, thrust tapered roller bearings, thrust needle roller bearings. Thrust cylindrical roller bearings are mainly used in petroleum rigs, steel, and steel machinery. Thrust self-aligning Roller bearings this type of bearings is mainly used in hydroelectric generators, vertical motors, marine propeller shafts, tower cranes, extruders, etc. 

Thrust tapered roller bearings The main purpose of such bearings: unidirectional: crane hook, oil rig turn Ring. Bidirectional: Rolling mill roll neck. Planar thrust bearing mainly bears axial load in the assembly, which is widely used.
