Choose a synchronous belt wheel is very necessary for equipment, so now many users when choosing pulley very notice whether belt wheel can realize optimization application, so what kind of pulley can realize optimization application? Choose good quality: like many other products, synchronous belt wheel at the time of application, also needs to have very good quality, will be in function and achieve good performance, service life and convenient application. So it is very good quality belt wheel, to realize basic optimization application ability. Suitable size. Because the pulley needs to be installed in the specific location of the main equipment in use, so its use effect inevitably related to the install state, and install state is its size is directly related to the structure, so the size must be suitable the pulley was able to finish the normal installation, such ability has the potential to realize optimization application. Has good property of the most important thing is that: synchronous belt wheel at the time of application, often need to contact with oily substance, at the same time also need to often friction, inevitable in this case the application requires a high degree of performance, performance is very good pulley is needed to realize the application of optimization.
