Ring type polyurethane synchronous belt without barge

Product Introduction

●Annular barge-free synchronous belt is made of imported thermoplastic polyurethane material and continuous strong surrounding steel wire frame. The product technology has reached the international technical standard with higher precision, and is suitable for high-speed power transmission and high-load transmission.
●The opening timing belt is made of thermoplastic polyurethane material, which has high wear resistance. Various types of reinforced cores ensure that it maintains good running ability in the transmission. During the production process, a layer of nylon is added to the tooth surface or tooth back to ensure the same operating characteristics in special applications. A layer of polyurethane or rubber can be thickened on the back to prevent corrosion and high load.

Product mechanical properties

●High precision, dimensional stability, small tolerance range
●Accurate right conveying, high transmission efficiency
●Good elasticity, strong tensile strength, good resistance to bending and winding performance, will not stretch
●Super wear-resistant, long service life

Chemical properties

●High temperature resistance and aging resistance
●Highly oil resistant. Can be used in most acid and alkali environments
●Working temperature -20 ℃ ~ 90 ℃
