Energysaving belts are specifically designed to cut operating costs. With a special lubricant applied to the running side, energysaving belts offer a very low coefficient of friction between the belt and the slider bed. Low friction means that less energy is needed to move the belt, so as a consequence, energy consumption is reduced.
