TRACK ROLLER IDLER

The materials available for Track roller and Carrier roller are 40Mn2?40MnB, depending on working conditions. The rollers are normalized with precision forging before overall heat treatment to achieve surface hardness of HRC52-62 and the depth of hardened layer reaches more than 7-10mm (HRC45),This ensures higher durability with high impact resistance and surface wear resistance on the contact surface of the rollers.High quality floating seals and lubricating system are used to adapt to different climate and temperatureThe track and carrier rollers is able to work under severe working conditions or climate ranging from -45?~120?, keeping the components free from maintenance.The idler is casted with alkali phenolic resin sand or sodium silicate-bonded sand process.Surface hardness reaches minimum HRC48-58 with hardness depth between 4-6mm (HRC45), after heat treatment process. The idler is able to withstand high impact and wear resistance under harsh working conditions.Production model: D5N; D6H; D6R; D65-8; D65-12; D8R/D8N; D9R/N; D10N; D11N; D155A-1; D155A-6R; D375?
