What Is a Slewing Ring?

Slewing rings are rotating bearings designed to support large-diameter shafts or high loads.

These bearings find applications in various sectors, including construction machinery for supporting rotating structures like cranes, renewable energy generation facilities such as wind turbines and solar panels for rotation mechanisms, and industrial robots or machinery for rotating elements like robot arms or industrial machines.

Characterized by their large diameter, slewing rings feature a rotating structure between the inner and outer rings. This design allows the outer ring to rotate around the inner ring, providing stability and reducing wear by functioning as a bearing against rotation.
