• Specifiion

• Function

1.Friction Reduction: Eliminates direct metal contact between pivot pins and structural components, reducing wear on both parts and extending their service life (critical for joints that move thousands of times daily).

2.Load Distribution: Distributes the heavy loads from the work equipment (boom, arm, bucket) across a larger surface area, preventing localized stress that could crack or deform the structural brackets.

3.Shock Absorption: The bushing’s material flexibility (bronze’s slight elasticity) cushions sudden impacts (e.g., during digging or loading), reducing vibration transferred to the excavator’s main frame.

4.Alignment Maintenance: Maintains precise alignment between connected components (e.g., boom and arm), ensuring smooth, predictable movement of the work equipment.
