Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
Excavator bucket pins are essential hinge components that connect the bucket to the arm or boom. They play a critical role in enabling lifting, digging, and material handling operations by supporting rotational movement under heavy loads.
This bucket pin is engineered to:
- Maintain tight linkage tolerances
- Withstand extreme radial and axial forces
- Support long-term field use in harsh environments
Material & Heat Treatment
Our bucket pins are manufactured using high-quality 40Cr, 45# steel, or 42CrMo, depending on size and usage scenario. To enhance strength and durability:
- Precision forging ensures dense grain structure
- Induction hardening on the surface raises hardness to HRC 52–58
- Quenching & tempering optimize both hardness and impact toughness
This combination offers excellent wear resistance and anti-bending performance.
Production Process Overview
Every pin undergoes strict multi-step processing:
- Sketch & CNC profiling – Shape precision based on machine specs
- Drilling – Accurate hole placement for grease channel or lock pin
- Heat treatment – Surface hardening and core strength optimization
- Polishing & grinding – Achieve micron-level finish and dimensional tolerance
- Seal fitting (if applicable) – Fitment of O-rings or dust seals for contamination control
- Anti-rust coating & packaging
Compatibility & Application Range
Our bucket pin catalog includes:
- Boom Pins – connect boom to the upper structure
- Arm Pins – connect boom to the arm
- Bucket Pins – connect bucket to the arm
- Link Pins – used for connecting H-link or link rods
