We specialize in manufacturing the whole set of undercarriage parts for 200 ton mining excavators. Now we have completed the pc2000-8 front idler, track and carrier roller, sprocket segment rim, chain assembly. More about the PC200-8 Track Roller advantages are as follows:

The material of PC2000-8  track roller body is forged by 40Mnb2. High wear resistant Boron steel ,and the surface heat treatment HRC 48-55 depth up to 5-8mm.  Precision CNC machine machining size is more accurate .Perfect interchangeability with original products

The material of the center shaft of the track roller forged by 42CrMo.The hardness of surface heat treatment can reach 48-55HRC More wear-resisting . Core hardness of HRC 28 or above is not easy to fracture. Tempering 180 degrees before finishing. The surface of the center shaft of the track roller is polished by CNC machine tool to make the shaft smoother.

High sealing aprons are used inside the track roller to prevent dirt, sand and water from damaging it.

The track roller using friction welding technology welding quality is good and stable, and environmental protection, no pollution.Welding process does not produce smoke or harmful gas, no splash, no lone light and spark, no radiation.Known as the green welding technology of the future.
