Raw edge belt

Vindustrialfriction

Raw-edge belts have cogs on the bottom section and forego the fabric wrapping on the outside of the belt, leaving the interior materials exposed on the sides. The belt, provided with a higher coefficient of friction, can now better grip the sheaves. This increased grip means that the raw-edged belt transmits more horsepower at higher speeds, as much as a 30% increase in some cases. Increased power is a substantial benefit of this type of belt. There are several other benefits worth mentioning, as well. Raw-edge belts, because of the inclusion of the cogs, are better able to wrap around smaller sheaves. These belts also run cooler at higher speeds and generally have better temperature resistance. Lastly, with the implementation of raw-edge belts, there is a potential for energy savings. Raw-edge belts run at slightly higher efficiencies than wrapped ones do.
