Slewing bearing is a kind of large bearing that can bear comprehensive loads, and can bear large axial and radial loads and tilting moments at the same time.
Slewing bearing is also called rotary bearing, some people also call it: rotary bearing, swing bearing.
English names are called: slewing bearing, slewing ring bearing, turntable bearing, slewing ring.
Slewing bearings are widely used in the real industry, is known as: "machine joints
Slewing ring bearing is widely used in real industry, it is called "the joint of the machine", it is the important transmission part which is necessary for the relative rotary movement between two objects, and also need to bear the axial force, radial force, and tilting moment of the machinery at the same time. With the rapid development of the machinery industry, slewing bearing in marine equipment, engineering machinery, light industry machinery, metallurgical machinery, medical machinery, industrial machinery and other industries have been widely used.
Slewing bearing industry in China has experienced more than 20 years of development, since 1984 for the first time released JB2300-84 "slewing bearing form, basic parameters and technical requirements" standard, as well as in 1999 revised JB/T2300-1999 "slewing bearing" standard, now China has a perfect slewing bearing design, manufacturing and testing of comprehensive development Now China has a perfect slewing bearing design, manufacturing and testing of comprehensive development capabilities.
