Komatsu PC75-Series Excavator Drive Sprocket High Corrosion Resistance

The PC75 Sprocket is a precision-engineered component designed for Komatsu PC75-series excavators, ensuring durability, excellent load-bearing capacity, and smooth operation in demanding construction environments.

This critical wear component in the undercarriage system plays a vital role in guiding the track chain, maintaining proper tension, and ensuring smooth track movement. It works in conjunction with rollers, idlers, and sprocket shafts to reduce friction, prevent track misalignment, and enhance excavator stability during operation.

• High-grade Material Selection: Components crafted from premium materials for maximum durability
• Outer Race/Shell: High-carbon chromium bearing steel (SUJ2) for superior hardness and wear resistance
• Inner Roller/Spindle: Alloy steel (SCM440) engineered to withstand significant radial and axial loads
• Seals & Lubrication: Nitrile rubber (NBR) seals for oil resistance with lithium-based grease for long-term lubrication
• Quality Assurance: All materials undergo thorough inspection for chemical composition and mechanical properties using spectrometers and hardness testers
