Bearing wheel type roller LR series

stainless steelwith ball bearing

Track rollers with cylindrical or crowned outer ring - type LR - 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. - Rollers are made of the high-quality bearing steel, processed by heat treatment and precision grind, and are filled with a long service life, high -grade and multi-purposes grease. Rollers take the metal shield (suffix KDD) or rubble seal (suffix NPP) to prevent the dust. YITONG also can provide the rollers with concentric or eccentric pivot. Some types of the rollers can be made from the corrosion resistance stainless steel.
