Track roller is the core load-bearing part of crawler crane undercarriage. It bears the whole machine load and ensures stable travel and steering on rough construction sites. Our track rollers fit major crawler crane brands including Kobelco, Manitowoc, Liebherr and Nippon Sharyo.

Our track rollers are forged from high-strength alloy steel with quenching and tempering heat treatment. They feature thick wear-resistant surface, great impact resistance and wear resistance, and resist cracking and deformation. Equipped with high-quality floating oil seals, the rollers block sediment and prevent oil leakage. Made strictly to OEM dimensions, they serve as direct replacement parts with easy installation.

We are a professional manufacturer and exporter of crawler crane undercarriage spare parts. We own complete production lines for forging, heat treatment and machining. Every part goes through multiple inspections including tensile test, impact test, hardness test and magnetic particle inspection to detect material defects and cracks, ensuring reliable quality.

We supply full-range undercarriage parts for crawler cranes with bulk delivery available. Our products export to many countries worldwide. With reliable after-sales support, we aim to be your trusted supplier of undercarriage components.
