缓冲托辊与其它托辊的表面区别：缓冲托辊表面应用的是橡胶包裹，而其它托辊产品的表面是光滑的不锈钢表面，这取决于各种托辊的具体性能及作用，其它托辊的主要作用是皮带的支撑和输送，故而减少托辊与皮带之间的摩擦力是非常重要的。而缓冲托辊的作用是支撑和减少冲击损伤，故而它更多的考虑的是托辊同皮带之间的冲击损伤。
Surface difference between cushioning idler and other idlers: rubber wrapping is used on the surface of cushioning idler, while the surface of other idler products is smooth stainless steel surface, which depends on the specific performance and function of various idlers. The main function of other idlers is to support and convey belt, thus reducing the friction between idler and belt. Friction is very important. The role of cushioning idler is to support and reduce impact damage, so it is more concerned about the impact damage between idler and bel
