Crossed roller slewing bearing
The single-row crossed roller slewing bearing is composed of two seat rings. It has a compact structure, light weight, small assembly clearance, and high requirements for installation accuracy. The rollers are arranged in a 1:1 cross and can withstand axial force, overturning moment and large radial force at the same time. It is widely used in lifting and transportation, engineering machinery and military products.
