Slewing Ring Bearing

Slewing rings are usually used for low revolution, carrying high thrust loads and/or combined with radial loads. They can be manufactured without teeth, with internal or external teeth, with balls and/or with rollers.

Depending on the application, Slewing rings are divided into four types:

1. Single-row ball slewing ring

●Four point contact bearing, balls arranged 1:1
●Two seat rings (one on inner- and one on outer ring)
●Compact structure
●Light in weight
●Axial load, radial load and tilting moment simultaneously

2. Single-row roller slewing ring
●Rollers are arranged crossways 1:1
●Two seat rings (one on inner- and one on outer ring)
●Compact in design
●Light in weight
●Small clearance
●Axial load, resultant moment and considerable radial force

3. Double-row ball slewing ring
●Eight point contact bearing, with same or different ball diameters
●Three seat rings
●Open fitting, convenient for installation purposes
●Suitable for large connecting structures
●Large axial load and tilting moment

4. Three-row roller slewing ring
●Three seat rings
●Suitable for highest axial loads and tilting moments
●Suitable for large connecting structures
