Compared to the non-metallic flexible coupling elastic element, Film Coupling Have high mechanical strength.. Features and applications: Compared to the non-metallic flexible coupling elastic element,Have high mechanical strength, load capacity, small size, light weight structures, transmission efficiency and high driving accuracy, reliability, easy assembly and disassembly features.Suitable for medium and high-speed, high torque shaft drive.Compared to the drum gear coupling, there is no relative sliding, do not need lubrication and sealing, long life, no noise, simple structure, the basic need maintenance features. Can partially replace the drum gear associated auxiliary device.Independent of temperature and oil slicks. With acid, alkali, anti-corrosion characteristics. Can be used for high temperature, low temperature and with oil, water and corrosive medium environmental conditions. Loads for a variety of mechanical devices changed little shaft drive, highly versatile, industrial countries has been widely used, is focused on promoting the application of high-performance flexible couplings din, diaphragm couplings can be used for high-precision high-speed conditions, in practical application of the general then the middle axis, two axes offset compensation to improve performance. JMI type - counterbore basic; JMIJ type - counterbore intermediate shaft; JMII type - no counterbore basic; JMIIJ type - no counterbore intermediate shaft;
