Excavator Undercarriage Track And Carrier Rollers

Friction and shock loads transmitted from the track chain create heat within the roller. To withstand this, several quality steps are taken in the manufacturing of Komatsu genuine OEM rollers. To help keep oil in and dirt out, rollers are constructed of long-wearing, heat-resistant material supported by rubber load rings To reduce friction and help extend roller life, Komatsu OEM rollers utilize highly polished shafts and bronze bushings For strength and long wear life, rollers have heat-treated tread and flange areas To help keep you up and running, heavy-duty mounting brackets secure rollers to track frames, allowing the transmission of shock loads throughout the track frame Reservoir cavities in roller shells and shafts feed lubricant throughout the roller’s interior to reduce damage-causing heat To provide absorption of shock loads and avoid brittleness, hardness decreases toward the inner bore; surface hardness of the outer shell reduces wear caused by friction Greater flange height on Komatsu OEM rollers provides maximum track alignment and machine stability under varying operating conditions Depending on the application, you can choose from a wide range of track rollers: Standard and single flange with internal lubrication, to offer track alignment during operation Cold weather spec, which has a different seal to withstand cold temperatures and maintain elasticity
