Komatsu D31 bulldozer undercarriage parts number list
PINGTAI manufacturers provide D31 series undercarriage components specifically designed to provide extended life and durability under the toughest operating conditions. Excellent after-sales service, warranty 6 months to 2 years. The function of D31 carrier rollers is to carry the track link upwards, make certain things are linked tightly, and enable the machine to work faster and more steadily . Our products use special steel and produced by new process. Every procedure goes through strict inspection and the property of compressive resistance and tension resistance can be ensured. 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.| Description: | Carrier Roller Mining Operation Heavy duty |
