The Importance of Bushings
Upper and lower bushings are essential for maintaining the efficiency and longevity of your hydraulic hammer. These bushings:
- Keep your point or chisel properly seated during operation
- Maintain correct profiles and contours for optimal tool performance
Worn bushings can cause misalignment of the tool with the piston, leading to:
- Cracked pistons
- Cylinder damage
- Seal damage
Our upper bushings are cross-referenced to Rammer part number 300316 for reliable compatibility and performance.
