Applications: RC models, Automotive, electric motors, home appliances, construction machinery, transmission shafts, gear shafts, pups, Bicycle and various kinds of professional machinery. Thrust ball bearing components: thrust ball bearings from the seat, shaft ring and ball cage assembly of three parts. With the axis of said shaft with the ring, and the shell with the said seat. Thrust ball bearing types: acceptance of the scenario of one-way and two-way thrust ball bearings thrust ball bearings. One-way thrust ball bearings can bear one-way axial load. Thrust ball bearings, can withstand a two-way axial load. Thrust ball bearings, which ring with the shaft. The installation of seat spherical bearing leaving it with self-aligning properties, can reduce installation errors. Thrust ball bearings can bear radial load, lower speed limits. Thrust Ball Bearings use: apply only to bear the side of axial load, low speed machine parts, such as crane hooks, immediately pump, immediately centrifuge, jack, speed reducer and so on. Shaft bearing ring, seat ring and the rolling body is separate from the assembly and disassembly can be separately.
