Our carrier roller is engineered to deliver a seamless fit for Komatsu PC120 and PC130-7 excavators, matching the exact specifications of the original equipment. Cross-referenced with part numbers KM2794, 203-30-00120, and 203-30-00231, this component ensures hassle-free installation without modifications, reducing downtime and keeping your operations running smoothly.

Constructed from high-strength alloy steel, the roller surface undergoes heat treatment to achieve a hardness of 58-62 HRC, providing exceptional resistance to abrasion, impact, and corrosion. Whether your excavator operates on construction sites, mining fields, or agricultural terrains, this carrier roller is designed to withstand heavy loads and extreme conditions, extending service life by up to 30% compared to standard aftermarket alternatives.

Featuring a double-lipped rubber seal with a metal dust cover, our carrier roller effectively prevents dust, dirt, and moisture from entering the internal bearings. Pre-filled with high-performance lithium-based grease, the component maintains smooth rotation and reduces friction, minimizing wear on critical parts and eliminating the need for frequent re-lubrication.

• Cost-Effective Solution: Premium durability at a fraction of the OEM price point.
• Global Compatibility: Ships worldwide with fast delivery options to minimize project delays.
• 6-Month Warranty: Backed by our commitment to quality, with full replacement coverage for defects in materials or workmanship.

1. Installation: Ensure the excavator is parked on a stable surface, clean the mounting area, and torque bolts to Komatsu's recommended specifications (refer to your machine's service manual).
2. Maintenance: Inspect regularly for wear, cracks, or seal leakage. Keep the undercarriage clean to prevent abrasive debris from accelerating component wear. Adjust track tension periodically to maintain proper alignment with the carrier roller.
