Slewing bearing and wheel bearing, slewing bearing usually consists of worm, slewing bearing, shell, motor parts, etc.
Because core part USES the rotary bearing, can also carry axial force and radial force and overturning moment.
The form a lot, but the structure of basic same.
Is between the two objects should be relative to rotary motion, but also need to bear axial force and radial force and overturning moment necessary important mechanical transmission of the original.
With the rapid development of machinery industry, rotary bearing in Marine equipment, engineering machinery, light industry machinery, metallurgical machinery industry has been widely used.
