How Does an Excavator Swing Bearing Work?
The swing bearing consists of two main rings:
-
Inner Ring: Attached to the undercarriage (fixed).
-
Outer Ring: Connected to the upper structure (rotates).
Between these rings are rolling elements (balls or rollers) that reduce friction. A gear ring (internal or external) connects to the swing motor, enabling rotation.
Key Movements Supported:
-
Rotation (360° continuous turning)
-
Load Handling (axial, radial, and moment forces)
-
Shock Absorption (from digging and lifting)
