Crusher parts Arm bushing
Heavy-Duty Arm Bushing for Single-Cylinder Cone Crushers

Precision Engineered by NMS – The Pivot Point of Reliability

Compatible with Metso HP/GP, Sandvik CH/CS Series & E Crushers

Engineering Breakthroughs

► Ultra-Low Wear Design

  • Material Science: Bimetallic composite structure

    • Outer layer: High-strength forged steel (HB 280-320)

    • Inner layer: Self-lubricating bronze alloy (CuZn25Al6)

  • Wear Rate: <0.05mm/1,000 hours in abrasive granite crushing

► Vibration Suppression

  • Helical Oil Grooves: Patented helix geometry maintains continuous oil film

  • Damping Capacity: Reduces eccentric shaft vibrations by 65% (ISO 10816-3 verified)

► Precision Alignment

  • CNC-machined concentricity tolerance: <0.03mm

  • Pre-embossed installation alignment marks eliminate mounting errors
