What is the role of the track roller of the track chain?
The E330 series undercarriage parts are specially designed to extend service life and durability under the harshest operating conditions.Excellent after-sales service, industry leading warranty period of 6 months to 2 years. The more advantages as following: The material of track 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 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.| Description: | Track Roller Mining Excavator Equipment |

THE E330 SERIES CONSISTS OF
Rollers at the bottom carry the weight of the machine as it moves and digs.The front roller holds the track chain in place on time, the machine is traveling, and acts as a shock absorber and chain tensioner Track rollers provide for the undercarriage clearance height. The combination of the link height and the installation height of the bottom roller defines the undercarriage height increase. Therefore, it is very important to choose qualified and high quality track rollerWhat are the advantages of E330 track roller production process
