Bando 8V1700 Power AceBando 8V1700 Power Ace narrow profile V belt transmits power more efficiently and effectively, delivering higher horsepower ratings than classical cross section belts. Power Ace should be considered for any new drive application, as they can transmit the same load as classical belts in 1 2 to 2 3 the space. The special bias cut angle of the cover fabric reduces stress as the belt bends around sheaves, lowering heat build up that shortens belt life.
