Rubber & PU Open End Belts
PRODUCT DETAILS:
CONSTRUCTION:
Rubber Open End Belts：
·Top rubber(CR HNBR) + Tensile member(Glass Fibre)+ Teeth fabric(Elastic Fabric)
PU Open End Belts：
·Stee+Nylon+Kevlar
FEATURE:
Rubber Open End Belts：
·It has the characteristics of good dynamic bending performance, good crack resistance, good water resistance, aging resistance, heat resistance, oil resistance, and abrasion resistance.
PU Open End Belts：
·The transmission is accurate, there is no slippage when working, and it has a constant transmission ratio；
·Stable transmission, with buffer and shock absorption capacity, low noise；
·High transmission efficiency, up to 0.98, with obvious energy saving effect；
·Convenient maintenance, no need for lubrication, low maintenance cost, suitable for medium and long distance transmission.
APPLICATION:
Rubber Open End Belts：
·Synchronous belts are widely used in Textiles, automotive & tire, tobacco, paper processing， printing machine and now, more and more timing belts are also demanded by refinement, steel factories ,medicine equipments etc.
PU Open End Belts：
