Extreme Durability & Wear Resistance
- Premium alloy steel: 42CrMo/20CrMo, quenched & tempered (same as OEM).
- Ultra–high hardness: HRC 72–88, resists abrasion in hard rock/concrete.
- Heat stability: Handles 40–140°C; no deformation under continuous heavy blows.
- Long service life: 2–3× longer than standard bushes; fewer replacements.
Superior Vibration Dampening
- Tolerance–controlled fit: Minimizes piston/chisel play; reduces hammer chatter.
- Shock absorption: Absorbs 30–50% of impact vibration; protects excavator carrier.
- Smoother operation: Less vibration = less operator fatigue & lower carrier wear.
