Is the specific products of different kinds of synchronous belt wheel and application performance, different specifications of the pulley, will not only have different sizes, at the same time also will have some different in terms of accuracy. And from the point of view of application, the application of different needs, and precision of the size of pulley, etc will have different requirements. And integrated these application requirements, you need user at the time of purchase pulley, try to choose the right products in the following ways: size: due to the different equipment and application requirements, appropriate use of synchronous belt wheel specific diameter and width is different, so the user at the time of purchase pulley, you should try to choose very suitable products in terms of size, can normal installation to their own devices, which in turn can achieve good application. Precision: right among different application requirements, for the synchronous belt wheel will have different accuracy requirement, and about the production of pulley, manufacturer also can according to your actual application requirements to determine the accuracy of different level. From this perspective, the user at the time of buying pulleys, you should try to choose suitable products in terms of accuracy. Users should choose as far as possible in these aspects above are very suitable synchronous belt wheel, can be enough, because pulleys and related equipment for yourself use bring great convenience.
