Maximize the durability and stability of your Komatsu excavator with these premium PC100/PC130 lower track rollers, engineered to OEM specifications for Komatsu PC100 and PC130 series machines. As critical components of the undercarriage system, these rollers support the excavator’s weight, guide the track chain, and reduce friction during operation.

Every roller undergoes rigorous quality testing to guarantee consistent performance in construction, mining, and earthmoving applications.

Core Selling Points

✅ Exact OEM Fit for Komatsu PC100/PC130
Precision-machined to match the original Komatsu track roller dimensions, mounting points, and bearing configuration. They install seamlessly without modifications, ensuring perfect track alignment and optimal undercarriage performance.
✅ Heavy-Duty Industrial Construction
Forged from high-grade alloy steel with deep heat treatment, these rollers offer exceptional hardness (HRC 55-60) and wear resistance. The precision-ground surface reduces track wear, while the reinforced housing resists impact and deformation.
✅ Advanced Sealing Technology
Equipped with a double lip seal system and grease-filled bearings, these rollers prevent water, dust, and debris ingress, eliminating premature bearing failure. The hermetic seal maintains lubrication even in wet or muddy conditions.
✅ Cost-Effective & Long-Lasting
Engineered to outlast standard aftermarket rollers by 2-3 times, reducing the frequency of replacements and lowering maintenance costs. Each unit is backed by a 6-month manufacturer warranty.
