The alternator serpentine belt we're researching and producing use high-performance rubber, high stress thermal tensile cord and wear-resistance fiber. Our products have good performance in the high strength, long life time and low noise sides which means we can effectively decrease the problems like belt crack, worn, delamination and noise and increase the drivers comfortable feeling and safety.
We promise to cooperate with partners to help them develop superior Fan Belt Car, Pk Belt, Htd Timing Belt and develop excellent business based on our platform. You probably feel secure and satisfy when copperate with us. We attach importance to every process and detail, strive to be perfect, optimize the construction scheme and effectively protect the maximum interests of customers.

Applications
Alternator drive belts widely used in Automotive industry.
Alternator serpentine belt wear analysis
① CHUNK-OUT
Appearance: Pieces or chunks of rubber material have come off the belt. When chunk-out has occurred, a belt can fail at any moment.
Cause: Chunk-out can happen when several cracks in one area move parallel to the cord line. Heat, age and stress are the primary contributors.
Solution: Replace with a Pioneer alternator serpentine belt, which is designed for greater flexibility and heat tolerance in today's smaller engine compartments.
② PILLING
Appearance: Belt material wears off from the ribs and builds up in the belt grooves.
Cause: There are a number of causes, including misalignment, new belt on worn pulleys, lack of tension or a combination of these factors. Pilling will occur most frequently in diesel engines, but is not isolated to them.
Solution: When pilling leads to belt noise or excess belt vibration, the belt should be replaced. Make sure the new belt runs on perfect pulleys. Check the tensioner and ensure proper belt tension on a properly aligned drive.
The implementation of internationalization usually starts from the entry of Wholesale Poly-V Alternator Power Serpentine Belt 4pk850 into the international market, that is, the implementation of international marketing mix strategy is the first step in the implementation of enterprise internationalization strategy. Through the establishment of a complete after-sales service system, the company accepts and uses customer feedback on products and customer requirements for products, which enables us to continuously update, iterate and improve product services and make us work harder to optimize products. We take it as our responsibility to promote the harmonious development of society, base ourselves on reality, and do our best to fulfill our social responsibility.
