Long wear parts@ supply high quality Sumitomo Track Roller/Sumitomo Lower Roller/Sumitomo Bottom Roller/ Sumitomo Rodillos Inferiores/ Sumitomo Rullo Inferiore. Our Track Rollers have a high hardness level of HRC52-60. They are manufactured using a through hardening system and spraying quenching system, in compliance with the stringent ISO System.
Long wear parts@ use advanced machining centres, both horizontal and vertical, to execute processes such as machining, drilling, threading and milling. This ensures the quality and precision of each component, maximising their lifespan and minimising production costs per hour.
Additionally, they feature good bronze bushings and a deep hardened wear surface. This ensures excellent wear resistance even in the most severe working conditions.
The bulldozer track rollers of Long wear parts@ are available in single flange and double flange options and are designed with dual shafts to reduce internal heat generation, can fit Caterpillar(CAT) /Komatsu /ESCO /Sany / Hyundai/ Hitachi/ Doosan/Liebherr/ Hensley /VOLVO/ Liugong/ Xugong/ MTG/JCB/H&L/Combi/ Case/John deere/Kobelco equipments.
