With the function of both v-belts and flat belts, ribbed belt has soft and tough property as flat belt and tight and effective property as V belt.

1. At the same condition, transmission power is 30% higher than common v-belt.

2. With tight transmission system, at the same transmission power, it occupies 25% smaller than common v-belt.

3. Flat and soft belt is suitable for not only transmission of small pulley but also high speed transmission with speed of 40m/s; besides, its characters as slight vibration, few heat diverge and steady working.

4. Anti-heat, anti-oil, anti-wearing out, few elongation and long life.
