• Specifiion

• Key functions

1.Linkage Pivoting: Enables critical movement of the boom, arm, and bucket—without it, the excavator/loader cannot perform digging, lifting, or material handling tasks.

2.Heavy Load Bearing: Absorbs and distributes extreme forces (e.g., when a bucket hits rock or lifts a full load), protecting fragile hydraulic components and structural brackets.

3.Wear Resistance: The hardened surface and precision fit minimize wear between the pin and bushing, extending the service life of both components and reducing maintenance downtime.

4.Structural Stability: Prevents linkage components from separating or shifting during operation, ensuring operator safety and avoiding costly equipment damage.
