- Key functions & working principle
| Working Principle |
1. Press-fit into the pivot housing (e.g., excavator linkage bracket) to create a fixed sleeve around the pivot shaft |
| 2. The shaft rotates inside the bushing’s inner diameter, with the lubricated/coated surface reducing friction between metal components |
| 3. The bushing absorbs radial loads (perpendicular to the shaft) and distributes pressure evenly across the housing, preventing localized wear |
| 4. Self-lubricating variants release stored oil/PTFE film during operation to maintain low friction; greased variants require periodic lubrication to replenish the oil film |
| Core Functions |
- Friction Reduction: Minimizes wear between pivot shafts and housings, extending the life of linkages, arms, and other moving components |
| - Load Distribution: Spreads radial loads across the pivot housing, preventing cracking or deformation under heavy loads |
| - Vibration Dampening: Absorbs shock and vibration from equipment operation, reducing noise and improving operator comfort |
| - Alignment: Maintains precise alignment of pivot shafts, ensuring smooth movement of excavator/loader/bulldozer working equipment (e.g., bucket, lift arm) |
