features slewing bearings are ball or cylindrical roller bearings that can accommodate axial, radial and moment loads acting either singly or in combination and in any direction.
They are not mounted on a shaft or in housing; the rings are simply bolted on the seating surface. The four point contact ball bearings are available in one of three executions:
-without gear
-with internal gear
-with external gear
slewing bearings can perform both oscillating (slewing) movements as well as rotating movements.
