List of spare parts

An excavator swing bearing (also called a slewing ring, turntable bearing, or rotary bearing) is a critical component that allows the upper structure (house) of an excavator to rotate 360 degrees smoothly while supporting heavy loads.

• Location: Installed between the excavator’s upper frame (where the cab, engine, and boom are mounted) and the undercarriage (tracks or wheels).

• Function: Enables full rotation while distributing weight and handling forces from digging, lifting, and swinging.

•  

Why Is It Important?

Without a properly functioning swing bearing, an excavator cannot:
✔ Rotate smoothly
✔ Lift heavy loads safely
✔ Maintain stability during operation
