Featuring 4 tapered roller bearings (2 in each hub), Elite rubber disc return rollers have a “quad bearing” design that withstands severe applications and allows the reuse of the axle assembly. Made with universal shafts, they come in 5-, 6- and 7-in. diameters. Standard rollers include 3/4-in. bearings; heavy duty rollers are equipped with 1 1/4-in. bearings. Stainless steel shafts are available for corrosive applications.
