回转支承在现实工业中应用很广泛，被人们称为：“机器的关节”，是两物体之

Slewing in real industry which is widely used, known as the: "joint machine", is the need for the relative rotary movement between the two objects, and the need to withstand the axial force, radial force, the mechanical roll moment required important transmission member. With the rapid development of the machinery industry, slewing ring in marine equipment, engineering machinery, light industrial machinery, metallurgical machinery, medical equipment, industrial machinery and other industries has been widely used.

Swing support is widely used in the real industry, known as:the "joint of the machine", is the two objects need to make a relative swing movement, but also need to bear axial force, radial force, tipping torque of the machinery necessary important transmission components. With the rapid development of the machinery industry, swing support in the ship equipment, construction machinery, light industrial machinery, metallurgical machinery, medical machinery, industrial machinery and other industries have been widely used.

The slewing bearing is widely used in the real industry, which is called "the joint of the machine". It is an important transmission part of the machine which needs to make relative rotary 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 ring has been widely used in ship equipment, engineering machinery, light industry machinery, metallurgical machinery, medical machinery, industrial machinery and other industries.<br>
