Process Highlights: From Raw Steel to Precision Bushings
We ensure consistent quality through controlled processing in each stage:
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.
Compatible Application Scenarios
These bushings are commonly installed in:
- Arm pivot joints
- Boom connection points
- Bucket hinge positions
- Slewing ring interfaces (as inner sleeves)
They're essential components that reduce mechanical wear and absorb load impact under demanding jobsite conditions.
