4.What we can do

We supply various types of Track Roller,idler,sprocket,carrier roller,track link with high quality. Good quality products and high service.

idler has important technical functions because these parts must support strongly all tracks without any waving or unbalance and also must help the track drive smoothly.

Idler covers sufficiently these main points not only with the strong body made by the best steel casting and the heat treatment but with the perfect guarantee against the oil-leakage with the good quality of Seal groups. Moreover, the hardness, HRC 50-65, of the round girth of Idler has so high that a long life can be possible.

5.Bulldozer Application

Undercarriage partsfor Komatsu, Caterpillar, Hitachi, Kato, Daewoo, Hyundai, Sumitomo, Samsung, Kobelco and etc.

Undercarriage is adopting through hardening system and spraying quenching system while complying with the stringent ISO System. We are able to assure the part has excellent wear resistance even in the most severe working conditions.

We are using advance machining centre,horizontal and vertical CNC machining to execute processes such as machining, drilling, threading and milling to ensure the qulity and precision of each component to ensure the accuracy of assembly dimensions. This is to maximize the life span of each component and minimize production cost per hour.

We can supply following model parts:
