The features of narrow b-belt: the transverse inflexibility is large ,the power of transmission is 50%-100% higher than the classic v-belt,the speed of transmission is 40m/s,and the efficiency of transmission is 95%.3V(400-14000)5V(1270-14000)8V(3000-16000)

Produced for transmission systems that operate in limited space,offer to high rotation transmissions and to powerful engines,belts are smaller than the conventional ones.
