• Specifiion

• Functions & advantages

1.Friction Reduction: By separating the pivot pin from the structural component, it prevents galling (metal transfer) and reduces wear on both parts—extending service life.

2.Load Distribution: The bushing’s cylindrical shape evenly distributes forces from the pin to the structural component, preventing localized stress that could crack or deform the boom/arm.

3.Vibration Damping: The bronze material’s slight elasticity absorbs vibrations during operation, reducing noise and improving operator comfort.

4.Easy Replacement: As a wear component, it is designed to be replaced periodically—protecting more expensive parts (pins, boom, arm) from damage.
