The Series LR/ Cam Roller with cylindrical or crowned outer ring 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 the roller is shaped to the crowned runner surface with R500 (suffix U), so make the stresses well when it is working. Products 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 products can accommodate higher loads.

After the cam roller assembled the concentric or eccentric pivot, installation can be made convenient. To adjust the eccentric one's eccentricity, the item can get the fitting reload. Besides we produce the LR series according to the standard of rolling bearings, we also make the strict control on the rotary accuracy of outer ring in order to meet special working mode that inner ring is fixed while outer ring running.
