Small thrust ball bearing 51209

        51209 is a small thrust ball bearings in Runspeed. It is with a bore size 45mm, and a outer diameter 73mm and a width 20 mm.Small thrust ball bearings are designed in those applications need axial load and low speed,but it can not support any radial load. 

             In order to facilitate installation and disassembly, as well as maintenance and inspection, the thrust bearing is designed as a separable component, and these components are composed of two washers and a retainer with balls, and all components can be replaced at any time.

       The material of 51209 is chrome steel for two washers, and stainless steel or brass for cages. It is a pop size for application as knife,scissor,  crane hook, vertical water pump, vertical centrifuge, Jack, low-speed reducer and platform lift etcs those need  medium speed and axial load.
