Fractional Fixed Bore with a groove is designed to fit a belt, rope or cable. In power transmission, pulleys will most often utilize a belt. Pulley drive includes one pulley on each shaft and one or more continuous belts over the two pulleys. Fractional Fixed Bore allows for mechanical power, torque, and speed to be transmitted across axes and, if the pulleys are of differing diameters, this ratio creates a mechanical advantage. Clients can avail this sheave from us in different specifications.
