Rotary Bearing of Machine Joints

Rotary bearing is an important transmission part of the machine which needs to rotate relative motion between two objects and bear axial force, radial force and overturning moment at the same time. With the rapid development of machinery industry, slewing support has been widely used in marine equipment, construction machinery, light industry machinery, metallurgical machinery, medical machinery, industrial machinery and other industries.

The slewing bearing industry has experienced more than 20 years of development in China. Since JB2300-84 Standard of Form, Basic Parameters and Technical Requirements of slewing bearing was first issued in 1984, and JB/T2300-1999 Standard of slewing bearing was revised in 1999, China has already possessed the comprehensive development ability of designing, manufacturing and testing slewing bearing.
