single-row four point contact ball bearing is mainly made up of inside and outside rings. Single-row four point contact ball ring has the features of compact in design, and light in weight. The balls roll on the circular race at four points, so it can undertake the axial force, radial force and tipping moment at the same time.
This series of four point contact ball bearings are suitable in many engineering machinery, such as rotary conveyor welding operation machine, small cranes, small and medium-sized excavators and so on.
