Kinton Parts is trusted by professionals worldwide for delivering high-quality parts for excavators, bulldozers, and other construction machinery—with guaranteed performance and durability.
The bucket pin is a critical connection point between the bucket and the excavator arm. It transfers powerful breakout force during digging and lifting, making it essential for smooth articulation and structural durability. Our bucket pins are ideal for general earthmoving, demolition, trenching, and quarry applications.
Production Process & Visual Highlights
All bucket pins are made from high-grade alloy steel (e.g., 40Cr or 45#), selected for strength and wear resistance. They undergo quenching and tempering, followed by precision grinding to achieve:
- High surface hardness (HRC 52–58)
- Deep wear resistance
- Impact toughness and bending strength
This ensures the pin resists fatigue, torsion, and abrasion under heavy duty use.
Manufacturing Process
Each pin is manufactured through strict machining and inspection steps, demonstrated in the following images:
- Pin Type Overview: A sketch showing various bucket pin styles used in arm, boom, and bucket connections.
- Drilling Process: CNC deep-hole drilling ensures accurate oil holes or grease channels.
- Precision Finishing: Polishing and deburring for optimal surface finish and easy bushing fit.
- Seal Kit Installation: Some pins are paired with matching dust seals or o-rings to prevent contamination and extend lifespan.
