Excavator Bottom Roller Track Roller For E320; PC220-5

Short Description:

The materials avaliable for Track roller and Carrier roller are 40Mn2、40MnB、50Mn,depending on working conditions.The rollers are normalized with precision forging before overall heat treatment to achieve surface hardness or HRC52-6 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 roller.High quality floating saels and lubrcating system are usde to adapt to different climate and temperature The track and carrier rollers is able to work under severe working conditions or climate ranging from -45℃~120℃,keeping the components free from miantenance.
Our Track Roller is welded before precision machining in vertical CNC turning lathe and hence,there is no concentricity errors.The process gives unparalleled quality quality advantage over that of precision machning before welding.Therefore,the operation of roller is be guaranteed against occurrence of rapid wearing problems,which significantly improves service life of the products.
