The PC100-5 Sprocket is Komatsu's precision-engineered component designed for excavators in demanding projects. This drive sprocket ensures durability, excellent load-bearing capacity, and smooth operation in construction machinery.

The PC100-5 sprocket is a critical wear component in the undercarriage system of the Komatsu PC100-5 excavator, playing a central role in transmitting power from the drive motor to the track. It works in conjunction with track links, rollers, and idlers to ensure smooth track movement, reduce friction, and maintain proper alignment.

Regular inspection and replacement of the sprocket are essential to prevent track slippage, uneven wear, and costly downtime.

Our production involves rigorous quality-controlled processes:

• High-grade Material Selection: Components are 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
