In addition to undercarriage parts, we also supply wear parts such as bucket , bucket teeth ,pin ,bushing and bolt nut etc... The heat treatment depth is uniform hardening so that the supplier wear life equals the link wear life. The material of the carrier roller body is forged by 40Mn2. and the surface heat treatment HRC 48-55 depth up to 5-8mm. Precision CNC machine machining size is more accurate The center shaft of the carrier roller material is 42CrMo and forged .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 carrier roller is polished by CNC machine tool to make the shaft smoother. High sealing aprons are used inside the carrier roller to prevent dirt, sand and water from damaging it. The carrier roller using friction welding technology welding quality is good and stable, and environmental protection, no pollution.
