Product description:
Precision bearing group specializing in the production of external teeth, internal teeth, non - tooth four point contact ball wheel bearings. Four-point contact ball rotary bearing is composed of four major parts: inner ring, outer ring, steel ball and isolation block. It has a compact structure, light weight, and four point contact between steel ball and arc raceway. It can bear axial force and radial force at the same time. It is often used in rotary conveyer, welding operator, medium and small crane and excavator.

he industry of slewing support has experienced more than 20 years of development in China. Since the standard jb2300-84 "form of slewing support, basic parameters and technical requirements" was first issued in 1984, and the standard JB/ t2300-1999 "slewing support" was revised in 1999, China now has a perfect comprehensive development capacity of designing, manufacturing and testing of slewing support.
