Driven conveyor roller RR-EX

nitrileneoprene®polyurethane

Product overview
Finned rollers feature circumferential grooves permanently bonded to a steel insert and are designed for shaft mounting. A hub extends beyond the roller and is supplied with two setscrews spaced 90° apart to secure the roller on the shaft. The grooved profile reduces contact area with the workpiece and channels dirt, debris and liquids away from the contact surface. Rollers are offered in Neoprene, Nitrile and Urethane with hardness options from 20 to 60 Shore A.
