Slewing bearings are a large bearing capable of withstanding integrated loads and can withstand large axial, radial and overturning moments.
Rotary support, also known as turntable bearings, some people also called it: rotation support, swing support.
English name are: slewing bearing, slewing ring bearing, turntable bearing, slewing ring
Rotary support in the real industry is widely used, is known as: "machine joints", between the two objects need to be relative to the rotary motion, but also need to bear axial force, radial force, tipping moment of the machinery Essential transmission parts necessary. With the rapid development of machinery industry, slewing support in the ship equipment, engineering machinery, light industry machinery, metallurgical machinery, medical machinery, industrial machinery and other industries have been widely used.
