The poly rib belt (poly v belt, serpentine belt) refers to a ring-shape rubber transmission belt with a flat belt as the base body, and vertical 40° trapezoidal wedge arranged on the inner surface with equal intervals, the working surface is the side of the wedge. It's especially suitable for high-speed transmission with compact structure and large transmission power.
Features
● The poly rib belt is thin and light, with good flexibility, reasonable structure, and low working stress, can work on smaller pulleys
● Small transmission vibration, fast heat dissipation, smooth operation, small use elongation, large transmission ratio and high ultimate linear speed
● The energy saving effect is obvious and the transmission efficiency is high.Compact transmission, occupy little space
● The back of the poly v belt can also be driven, and automatic tension adjuster can be used to make the transmission more safe and reliable

Applications
The applications of serpentine belt in the automotive and industry, such as for car engine belt, industrial dryers, fitness equipment, electric tool, high speed blowers, and so on.
Production Details
1. Reinforced CR and EPDM material to ensure better wear resistance and high temperature resistance
2. HMLS Polyester: Less elongation give maximum power transmission
Aramid fiber reduce noise
TIPS
Wedge damage occurs in the use of poly rib belt
① The specifications and models of pulley and the poly rib belt do not match;
② The belt wedge is stained with solvent or other chemicals;
③ The use environment temperature is too high, the cooling method should be improved.
④ The process parameters of the pulley do not meet the standard or the pulley is rusty.
Precautions for purchase of V-ribbed belts
According to the pulley diameter and wedge groove, select the belt with the appropriate specification model and number of wedges
