slewing bearing
Slewing bearing supports combined radial, axial and over turning moment loading. It belongs to large-size bearing. The structure of slewing bearings is always with mounting bore, lubrication oil bore, sealing device and internal gear or external gear. For above-mentioned reasons, slewing bearing has many characteristics such as having compact structure, convenience of mounting and dismounting, so on.
There are various structures of slewing bearing, for example, four point contact ball bearing with gear internal toothing, gear external toothing and without gear toothing, double direction angular contact thrust ball bearing, bearing with crossed cylindrical roller, bearing with crossed tapered roller and three row cylindrical roller multi-part bearing, etc.. Four point contact ball bearing has higher capacity of dead load, while bearing with crossed cylindrical roller has higher capacity of live load and bearing with crossed tapered roller has higher rigidity and running accuracy.
