• Specifiion

• Function

1.Friction Reduction: Minimizes wear on pivot pins and structural bores by separating moving metal surfaces—critical for extending service life in high-stress applications (e.g., digging through rock).

2.Load Distribution: Spreads concentrated forces from the pivot pin across a larger surface area of the structural component, preventing cracks or deformation in the arm/boom.

3.Vibration Damping: The bronze material’s slight elasticity absorbs shock loads (e.g., when the bucket hits hard ground), reducing noise and stress on the entire work equipment assembly.

4.Alignment Maintenance: Ensures the pivot pin remains centered in the structural bore, preventing uneven wear and maintaining smooth, predictable movement of the boom, arm, or bucket.
