Description
Sur-Grip® is a tungsten-alloy granular coating that is applied into the vees of the pulleys with a process called Electrofusion. This process creates a true metallurgical bond with the pulley and very high bond strength. The granular surface allows the rubber in the belt to “key” into the pulley, greatly increasing its tractive force. In addition to increasing the surface friction for the belts, it also increases the surface hardness of the material up to 72Rc, making the pulley itself more durable also.
