We can produce flange slewing bearings that satisfy customers is because we have mature flange processing technology. Generally speaking, our product raceway hardening treatment is intermediate frequency quenching and the large internal stress generated by temperature difference fusion cannot eliminate internal stress due to the large size of the flange but small cross-sectional area, resulting in excessive deformation.

The four-point contact ball slewing bearing with flange is designed and manufactured to accommodate more applications. This slewing bearing does not have teeth, and the inner and outer rings are flanged. It belongs to the light series of slewing bearings. Featuring flanges on the outer ring, the slewing bearings make the axial positioning simple.

Flanged slewing bearing is same in structure with other slewing bearings, featuring light weight and flexibility. There is a L-shape fringe on the outer or inner ring of flanged slewing bearings, resembling a flange. That is why it is called flanged slewing bearing.

Designed without bearing seat, the ball slewing bearing 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. Adopting hollow shafts ensures light weight and wiring space. Flanged slewing bearings mainly bear radial loads, and they can also bear radial and axial loads at the same time.
