Different from standard heavy‑duty slewing bearings, this model features an extremely slim cross‑section with smaller steel ball rolling elements.
This design brings two major manufacturing challenges.
1. Rigidity control during gear cutting
Oversized thin rings are prone to deformation under clamping and cutting force. Our fixture is custom built to hold the workpiece evenly, avoiding distortion while hobbing the outer gear teeth.
2. Precision tooth profile tolerance
Even tiny deformation will cause uneven gear meshing, shorten service life and create vibration during continuous rotation on farm equipment.
Our technical team adjusted the hobbing feed rate, cooling flow and clamping distribution before formal machining.
These ultra‑thin large slewing rings are widely used on modern harvesters and agricultural rotary equipment, where customers require lightweight structure while keeping sufficient rotation load capacity.
If your project needs custom ultra‑thin, large diameter slewing bearings for farm machinery, welcome to send us your drawing for technical review and quotation.
This 26‑second footage shows gear cutting for a custom large ultra‑thin slewing ring, produced for our agricultural machinery customer from Turkey.
Compared with conventional slewing bearings, this series adopts an ultra‑thin structure and smaller steel ball rolling body.
The thin‑wall design makes gear hobbing much harder. Special clamping tooling is required to prevent workpiece deformation and guarantee high‑precision gear teeth.
Lightweight large slewing rings are popular for new generation agricultural harvesters.
