Fenner offers imperial v-grooved pulleys, made from better quality cast iron. These pulleys conform to is and iso groove specification and are property balanced and precision made to perfectly match v-belts to transmit higher loads and thus enhance the v-belt life. In addition, the pulleys are phosphated and have rustproof property.

Hub diameters are designed to accommodate larger shaft diameters.
