CAT Full Series excavators

Our range of track rollers and carrier rollers is designed to withstand the most demanding mining and earthmoving environments. Through advanced material technology and precision manufacturing processes, we deliver exceptional undercarriage durability. Superior Wear Resistance: The roller bodies are forged from alloy steel and undergo deep-hardening heat treatment, significantly enhancing surface hardness and core toughness to resist long-term rolling wear. Excellent Sealing Protection: Equipped with specialized "Duo-Cone" floating seals, these components are resistant to high temperatures and pressures; they effectively block the ingress of external grit, moisture, and corrosive mud, ensuring the long-term stability of internal lubricants. High-Precision Bushings and Bearings: We utilize wear-resistant alloy bushings that offer excellent anti-seizure and self-lubricating properties, ensuring smooth rotation under heavy loads. Broad Compatibility: Precision-engineered to fit major excavator and bulldozer brands (such as Komatsu, Caterpillar, Hitachi, Sany, Volvo, etc.), allowing for seamless, modification-free installation.
