There are two contact points between the roller and track, so the contact functionis favorable.Rollers feature double row angular contact ball bearing in its internal structuredesign and a thick-walled outer ring, so rollers can accommodate higher loads.Rollers are made of high-quality bearing steel, processed by heat treatment andprecision grind, and are filled with a long service life, high-grade and multi-purposesgrease. Rollers mount the metal shield (KDD) or rubble seal (NPP) to preventthe dust. We also can provide the rollers with concentric or eccentric pivot.Some types of the rollers can be made from the corrosion resistance stainlesssteel.
