PU synchronous belt is made of thermoplastic polyurethane.It has strong anti-wear.The various of steel wire cores ensure the sound running capability in the driving. It has small production tolerance.Open-end PU synchronous belt has the reliable transmission and the fine size stability. A layer of nylon can be added in the tooth face and/or back in order to guarantee the running specialty in the special applications, also can added a thick layer of polyurethane in the back of the belt to resist corrosion or high loading.
