D4 Carrier Roller Part Number 6K9880/3K7962/6K9879
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.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.
