Heavy duty slewing ring gear bearing for crane turntables
✔️ Fits base frames on crane models 011.20.400 and 011.20.200

This slewing ring gear turntable bearing delivers solid rotational stability for heavy lifting rigs and support structures. It typically serves as a direct swap for worn rotary joints on rigged work sites, keeping boom sections spinning smooth and locked tight under constant stress.

✅ Handles maximum axial and radial loads during heavy lifts
✅ Precision ground gear teeth ensure slow and steady rotation
✅ Single color coating stands up to harsh job site dust
✅ Pre-drilled bolt circles line up with original mounting plates

💡 How do slewing ring gear bearings transfer load on mobile cranes? A slewing ring gear bearing channels massive axial and radial forces into the main frame while allowing controlled pivoting action. It is a really handy piece of hardware for keeping heavy booms steady when jobs get heated. When you swap out your rotary joint assembly, watch these quick tips: - Align pitch circle diameters with existing drive motors - Verify outer race thickness against static support columns - Pick cross roller cages that seal out workplace humidity - Install fresh inner tracks to erase play during boom shifts
