Although a synchronous belt wheel is high quality, the key lies in whether it has good quality and texture quality structure, but how is that there is a definite relation and its surface quality. And all when the choose and buy the product, is also very need to focus on the surface quality of the product exactly how. Say you at the time of purchase of synchronous belt wheel, need to focus on its surface quality, it is just because of the pulley surface quality, directly determines the performance of its have the how, and the performance of the pulley, and its service life, etc. There is a lot of contact, especially corrosion resistant, wear resistant performance, such is how long it will directly affect the belt wheel is able to use. So from the service life of belt wheel side, it is very necessary at the time of purchase pulley, pay close attention to its surface quality. Synchronous belt wheel surface quality, and the quality of this at the same time, will also affect its at the time of application, there will be a change in the surface part. If its not a very good surface quality, for example, the surface is very easily in the process of constant friction is becoming more and more smooth, so it is possible to make equipment at the time of movement, synchronous belt slippage phenomenon appeared. But if the pulley have good surface quality, then is to be able to because the surface of the wear-resisting performance is good enough, and more can guarantee its in many a time have normal running state. So from the service life of the synchronous belt wheel and optimized using ways, such as when the choose and buy pulleys on its surface quality is necessary
