Flange Slewing Bearings
The series of turntable bearing slewing bearings with flanges on the outer wheel make axial positioning simple. The bearing seat is no longer needed, and it becomes more economical. In order to obtain the low friction torque, high rigidity, and good rotation accuracy of the bearing, a steel ball with a small outer diameter is used. The use of hollow shafts ensures lightweight and wiring space. Flanged slewing bearings mainly bear radial loads, but they can also bear radial loads and axial loads at the same time.

The flange slewing bearing has the same structure with four points contact ball slewing bearing, but the weight is lighter; the outer or inner ring of the flanged slewing bearing has the “L” edge, like a flange. That’s why we called it flange type bearing. A flange light slewing bearing ring is also working in some applications which have a weight limit for the bearing. The weight for the flange type slewing ring is much lower than the standard type. The materials of the flange slewing ring are mainly 50Mn, 42CrMo, and C45.
The flange slewing bearing rings has been widely used in many applications:
- Food machinery
- Canning machinery
- Environmental machinery
- Car parking systems, etc.
