Thrust bearings are one of particular separable ball bearings, they are composed of shaft washer,housing washer and steel balls with cage. And shaft washer is designed to fix the shaft, and housing washer is designed to fix the parts outside the shaft. Compared with deep groove ball bearings, thrust bearings can not support radial load or high speed, it can only support axial load and mediunm speed in application.
According to the force direction,thrust bearings are divided into unidirectional thrust bearings (one-way thrust bearing) and bidirectional thrust bearing(two-way thrust ball bearing). Unidirectional thrust l bearing can only support unidirectional axial load. And bidirectional thrust bearing can support bidirectional axial load.
There are miniature thrust bearing and small thrust bearings.
F2.5-7M is belong to miniature thrust bearings,it is a customized thrust bearings with a bore diameter 2.5mm and a outer diameter 7mm, it is designed for special application.
Usually thrust bearings are widely used in crane hook, vertical water pump, vertical centrifuge, Jack, low-speed reducer which only need one side of axial load and low speed. Zhangzhou Runstar Bearings Manufacturing Co.;Ltd is a professional thrust l bearings factory since 2007,certified ISO9001:2015.Runstar has more than 15 years in designing and manufacturing thrust bearings for industries, customized thrust bearings are accepted in Runstar.
