Expect Lasting Quality with Komatsu Genuine OEM rollers

Depending on the application, you can choose from a wide range of dozer and excavator track rollers:

  • Standard, single flange and double flange: for standard rollers
  • PLUS, Single Flange and Double Flange: with increased tread depth and flange height. Designed and manufactured with internal lubrication. 
  • Cold Weather Spec: this track roller has a different seal to withstand cold temperatures and maintain elasticity.

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.

  • Komatsu rollers are constructed of long wearing, heat resistant stellite material supported by rubber load rings that keep oil in and dirt out 
  • Highly polished shafts and bronze bushings are used in Komatsu OEM rollers to reduce friction and extend roller life
  • Rollers have heat treated tread and flange areas for increased strength and longer wear life
  • Heavy duty mounting brackets secure rollers to track frames allowing the transmission of shock loads throughout the track frame, thereby reducing potential damage
  • Reservoir cavities in roller shells and shafts feed lubricant throughout the roller’s interior to reduce damage-causing heat
  • Surface hardness of the roller’s outer shell reduces the wear caused by friction. Hardness decreases toward the inner bore to avoid brittleness and provide absorption of shock loads
  • Greater flange height on Komatsu OEM rollers provides maximum track alignment and machine stability under any operating conditions
