Pulley Lagging Rubber

RM Biltrite™ Rubbermax™ Pulley Lagging Rubber is used as a protective surface to improve and extend pulley life. It is applied to the pulley exterior, protecting the metal shell from wear damage. Lagging rubber enhances friction between the belt and pulley, resulting in improved grip, better water shedding, and less belt slippage. Cost effective and easily replaceable. Bottom can be provided sanded, fabric, or with a neoprene bonding layer.
