Four point contact ball slewing bearing design

1. Description

This series of single-row four point contact ball bearings 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.

2. Application

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. Such as 4 point contact ball Slewing Ring is well used for Truck Mounted Crane
