These high-precision bushings are used in critical pivoting points of excavators — including boom, arm, and bucket joints — to reduce friction and extend the life of mating pins and components. As long as the inner and outer diameters match, these bushings can be used across multiple brands and models, such as Caterpillar, Komatsu, Hitachi, Kobelco, Volvo, and more.
Material & Heat Treatment
Made of high-strength 40Cr alloy steel, this bushing undergoes:
- Quenching & Tempering: Enhances hardness and tensile strength.
- Surface Hardening: Achieves outer layer hardness up to HRC 50–58 for exceptional wear resistance.
- Fine-grain structure: Ensures consistent performance under repeated stress.
Material & Heat Treatment
Surface Machining & Finishing
The outer surface is finely ground and chamfered for easy press-fit installation and improved contact.
CNC Machining with Oil Grooves
High-speed CNC lathes cut precise oil grooves that help distribute grease during operation, minimizing internal friction.
Tempering Heat Treatment
Bushings are tempered at controlled temperatures to improve impact resistance and structural stability.
Hardness Inspection
Each batch undergoes random hardness sampling tests using Rockwell HRC testers to ensure reliable performance.
Application Areas
These bushings are commonly used in:
- Excavator bucket linkage pins
- Boom-arm pivot joints
- H-link and bucket rod ends
- Other wear-prone, load-bearing pin interfaces
