Fixed Bore Sheaves are used for transferring rotary motion between two shafts. The offered drive sheaves include one pulley on each shaft and one or more continuous belts over the two sheaves. This allows for mechanical power, torque, and speed to be transmitted across axes and, if the sheaves are of differing diameters, this ratio creates a mechanical advantage. The motion of the driving pulley is, generally, transferred to the driven pulley via the friction between the belt and the pulley. Besides, these Fixed Bore Sheaves are available at marginal prices.
