• The transmission power is large, the transmission efficiency is high, and the transmission power of the ordinary V-belt is 30% higher than that of the ordinary V-belt at the same time, and the energy saving effect is obvious.
• The transmission is compact. Under the same transmission power, the space of the transmission device is 25% smaller than that of the ordinary V-belt.
• The back of the multi-ribbed belt can also drive, and an automatic tension adjuster can be used to make the drive safer and more reliable.
• The multi-rib belt offers the flexibility of a flat belt while delivering the high-power transmission performance of a traditional V-belt.
• Fit for many industrial machinery, appliances, and power tools, such as small compressors, pumps, lawnmowers, drills, and saws.
