The track roller for excavator and bulldozer is the first heavy equipment part launched by our company. Now, the full range of models make our product suitable for the brands such as Komatsu, Hitachi, Kobelco, Hyundai, Caterpillar, Mitsubishi, Sumitomo, Case, and Volvo, etc.
PC300-5
The track roller is composed of 40Mn2 forged shell, QT450-10 collar, and 40Cr axis, which are conducive to the longer lifespan of our product. In addition, the seal from the famous brand in Qingdao city effectively prevents the occurrence of oil leakage. Instead of the elastic pin, we particularly employ the precisely machined lock pins for the track roller. The shell and the axis are processed with quenching and tempering technology. For high performance, the surface of the bottom roller is manufactured with intermediate frequency heat treatment technology. The guarantee period of our product is up to 12 months.
