Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
Bucket pins serve as critical pivot joints between the excavator arm, link, and bucket. They bear the force of digging, lifting, and swinging, enabling smooth joint movement and reducing wear between components.
Typical applications include:
- Arm-to-bucket connection
- Boom-to-link rod joint
- Link-to-bucket hinge point
- Suitable for both crawler and wheeled excavators
Material & Surface Treatment
To ensure strength, toughness, and wear resistance, our bucket pins are made from:
- 40Cr or 45# Alloy Steel
- Induction-hardened surface layer (HRC 55–60)
- CNC-turned finish for perfect roundness
- Anti-rust oil coating for extended shelf life
Optional features include:
- Grease holes or grooves
- End holes or retainer ring slots
- Seal compatibility with matching bushings
