Steel conveyor roller RR-Bx

nitrileneoprene®urethane

Description
Solid rollers are single-piece industrial rollers with a steel insert permanently bonded to the outer material and radial bearings retained by snap rings. Designed for conveyors and material-handling equipment, they provide consistent outer diameter and are offered in multiple compounds and hardnesses. Supplied with standard bearings; precision and sealed-bearing options are available in other product types.

Product Types
