A plane bearing, thrust bearing is also called plane needle roller bearings or thrust plane needle roller bearing, thrust bearing radial needle roller bearing has the advantages of compact structure, plane diameter size and load capacity and other types of bearing at the same time, minimum diameter, especially for radial support structure and installation size restricted. The thrust plane needle roller bearings use according to different occasions,can choose the inner ring bearings or needle roller and cage assemblies, the shaft necksurface and the surface of shell holes matched with a bearing directly as bearing inner. The outer rolling surface, in order to maintain the load capacity and operating performance and have the same ring bearing, shaft or housing holes raceway surface the hardness and surface machining accuracy and surface quality shall be similar raceway of the bearing rings. These bearings can only bear radial load. Plane thrust needle roller bearings byplane with a needle or cylindrical roller cage assembly and flat washers. The main types are: AXK/AX/AXW/NTA plane thrust K811/K812/K89thrust cylindrical roller and cage assembly.

AXK type thrust needle roller and cage assemblies is a main component of thrust needle roller bearing. The holder with cold forming steel plate, the small cages are made from plastic, the high accuracy of G2 grade needle, so as to ensure a uniform load distribution.Thrust cylindrical roller and cage assembly and similar type AXK module, which can endure high thrust load.

The production of imperial thrust needle roller and cage assembly and supporting the use of pads, such as TC, TWA, TWB, TWC series.

AXW type needle roller thrust bearing is composed of a AXK type thrust needle roller andcage assembly components and a stamping center set.

The main components of AX type needle roller thrust bearing is AXK component and the thrust washer, and a control ring two are connected into an integral body.

2 thrust washers

The thrust washer mainly high quality spring steel strip (sheet) stamping, thicknessdepending on customer needs. The washer after quenching - Plastic - polishing. He is mainly used for adjacent parts cannot be quenched, but with sufficient rigidity and geometrical accuracy of the occasion, the support surface should be completely thebearing washer.

The shaft ring WS, ring GS and bearing washer is made of bearing steel LS quenchedentity washer, surface grinding and polishing, outer surface and the inner hole of the shaft ring seat by grinding. Entity washers general and thrust cylindrical roller and cageassemblies.

Type NTA is a British size thrust needle roller bearings, bearing structure and manufacturing process to be more complex than the AXK type.

Use the plane thrust bearing is very extensive: automobile, motor, electrical appliances,machinery, furniture, toys, printer, engineering machinery, sewing machine, packaging machinery, printing machinery, food chemical machinery, machine tools, textile machinery,fitness equipment, electronic products etc..
