What is a slewing ring?
Slewing ring can withstand a large-scale integrated load bearing can withstand large axial, radial load and overturning moment. Slewing ring turntable bearings called, some people also call it: the rotary support, swing support. English names were called: slewing bearing, slewing ring bearing, turntable bearing, slewing ring.
Slewing ring in real industrial applications is very broad, known as: "Machine joint" is subject to the relative rotational movement between two objects, but also to simultaneously withstand axial and radial forces, tilting moment by machinery required important transmission components. With the rapid development of the machinery industry, slewing bearings in marine equipment, engineering machinery, light machinery, metallurgical machinery, medical equipment, industrial machinery and other industries it has been widely used.
Slewing bearing industry in China has experienced 20 years of development, the first release since 1984's JB2300-84 "slewing ring form, the basic parameters and technical requirements" standard, as well as revised in 1999 JB / T2300-1999 "slewing ring" standard, now China already has a sound slewing bearing design, manufacture and testing of integrated development capability.
