  • slewing bearing wear measurement – Slewing ring

    2021-1-20 · Slewing bearing raceway wear is usually noticed by reducing or changing the axial motion. According to the actual application, raceway wear can be determined by reducing or tilting clearance measurements. The wear of the transmission device largely depends on the actual application.

  • 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.
