The Cogged Belts are very useful and have slots that run perpendicular to the belt’s length. The slots reduce the belt’s bending resistance. The belts can be used with the same pulleys as equivalently rated V-belts. They run cooler, last longer, and have an efficiency that is about 2% higher than that of standard V-belts. The belts are narrow belt profile transmits up to three times the horsepower of standard cogged V-belts for use on heavy duty drives with shock loads. They are available in various types and designs for being used in the various places. Cogged Belts are very efficient.
