As you know, at the time of purchase of synchronous belt, need to do a good job in the choose and buy of products can only be because use to product high quality and suitable enough, when to actually use the product, to ensure that the relevant equipment have good enough to run the transmission effect. To check the number of choose and buy the products, you need people at the time of purchase products, to consider the following questions: question one: what is the size of the product you need. Due to the different applications have different equipment structure, and to the equipment of different structure, you need to use the synchronous belt width and length will have some different. From this perspective, everyone at the time of purchasing the product, you need to consider themselves need to use what is the size of the product. Question 2: what kind of performance of the products you need. Due to the use of different applications have different strength, need to be synchronized with the external factors of influence is also different, under it from this perspective, everyone at the time of purchasing the product, you need to consider what you need is what kind of performance of the product.
