Power transmission belting has been used for more than 200 years. The first belts were flat and ran on flat pulleys. Later, cotton or hemp rope was used with V-groove pulleys to reduce cogged v belt tension.

This led to the development of the vulcanized rubber V-belt in 1917. The need to eliminate speed variations led to the development of synchronous or toothed cogged v belts about 1950 and the later development of fabric-reinforced elastomer materials.

Today, flat, V, and synchronous belting is still being used in power transmission. When compared to other forms of power transmission, cogged v belts provide a good combination of flexibility, low cost, simple installation and maintenance, and minimal space requirements.
