LR SERIES - Track rollers with cylindrical or crowned outer ring

  • Series LR rollers are also called CAM ROLLERS, can be used in the heavy loads track or used as an idler wheel. They are widely used in the particular application that the friction should be reduced.

  • The outer diameter surface of rollers is shaped to the crowned runner surface with R500 (suffix U), so make the stresses well when rollers working.

  • Rollers take the internal structure design of deep groove ball bearings or double row angular contact ball bearings and have a particularly thick-walled outer ring, so the rollers can accommodate higher loads.

  • Suffix KDD as Metal Seals & Suffix NPP used for Rubble seal to prevent the dust
