  • The application of slewing bearing

    2019-2-16 · The application of slewing bearing. Slewing bearing (slewing ring) is a kind of large rolling bearing that can carry axial loads, radial loads and overturning moments, and with high load capacity. The biggest feature of the slewing bearing is that it has large overturning moments (eccentric load), which makes the slewing bearing have a very wide range of applications.
