The service life of belts, tensioners, and idlers is the same. We suggest that if one of the accessories is replaced, it is best to replace the other accessories together, which is more conducive to the normal use of the accessories and extends the service life of the engine
Binopoly tensioner is composed of high-strength iron or aluminum alloy body, high-efficiency and wear-resistant elastic device, and a reasonable combination of damping plates, combined with a low-noise and high-speed operating pulley,to better maintain engine operation and extend engine life
