Segmented sprocket ring for bulldozer
The SEM 544-4537 Sprocket Segment is a genuine OEM-specification undercarriage component designed for the SEM 816D bulldozer/tractor. This sprocket segment is part of a segmented sprocket design, where multiple segments bolt together to form the complete drive sprocket ring.
The segmented sprocket design allows for individual replacement of worn segments rather than replacing the entire sprocket, significantly reducing maintenance costs and downtime. Each segment features precision-machined tooth profiles for optimal engagement with the track chain.
| Feature | Benefit |
|---|---|
| Segmented Design | Individual replacement reduces maintenance costs |
| Induction-Hardened Teeth | Exceptional wear resistance and extended service life |
| Precision-Machined Profile | Optimal engagement with track bushings for smooth operation |
| High-Strength Alloy Steel | Maximum durability for demanding applications |
| 816D Optimized | Specifically engineered for SEM 816D bulldozer |
| Direct OEM Replacement | Guaranteed fit and performance |
| Lightweight (8 kg) | Easy handling during installation |
