How do I determine the loads on a bearing? - Bearing Tips

19/6/2017· Those are the three basic load components on the bearing. We have to consider the weight of the component, the force and the drive forces. In this case it was a belt, but it could be chain driven or gear driven. And then you have the fly bills. If we know the distances, we can use stats to determine the load on the bearing.

The appliion of slewing bearing

The appliion 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 appliions.
