• Specifiion

• Design & Working Principle

1.Friction Reduction: The bronze alloy’s low coefficient of friction minimizes metal-to-metal contact between the hard steel pin and housing, preventing galling (metal transfer) and excessive wear during pivoting movements (e.g., when the arm lifts or the bucket rotates).

2.Load Distribution: The bushing’s cylindrical shape evenly distributes radial and axial loads across the pivot joint, reducing stress concentrations that could crack the housing or bend the pin.

3.Shock Absorption: The bronze material’s slight elasticity absorbs impact loads (e.g., when the bucket hits hard ground), protecting the joint from sudden stress damage.

4.Alignment Maintenance: By maintaining a precise gap between the pin and housing, the bushing ensures smooth, controlled movement of the work equipment, preventing "play" or instability during operation.
