Because everyone in the use of synchronous belt wheel, are cooperating with synchronous belt products to use, and among different applications, for many aspects of pulleys are have different requirements. So for you, need to use, is very applicable pulley in all aspects. Specifically, you need to use is suitable belt wheel in the following ways: first, material: right supply in the market have a lot of different metal materials such as steel, brass made of synchronous belt wheel, and different materials of pulley in terms of performance is suitable for application environment there is a difference. So for you, need to use is very appropriate pulley in terms of material. Second, the inner hole form suitable: supply of synchronous belt wheel products in the market, its pore structure, there are many different forms. So for you, need to use, also is in the form of internal control is the application of appropriate oneself pulley. Third, the suitable size: according to the different equipment or synchronous belt products, is suitable for the specific use of synchronous belt wheel size may be different. So for you, need to use the belt wheel, also need to be very well in terms of size. For any synchronous belt wheel user need use is above these aspects are very suitable pulley products.
