JMII Double-Diaphragm Coupling

The JMII Series Disc Coupling is a high-performance metal disc coupling that adopts a single-piece design without a sunk hole, offering a more compact structure specifically designed for applications with shorter transmission distances. It plays a crucial role in industrial transmission systems by connecting the power source to the driven mechanism, transmitting torque, and compensating for shaft misalignment. As the demand for high precision, high reliability, and low maintenance in industrial equipment continues to rise, traditional couplings are increasingly unable to meet the complex working conditions. The JMII disc coupling, with its excellent transmission performance and unique structural design, has become the ideal choice for improving system efficiency and stability.
This coupling consists of two sets of stainless steel disc components and two half couplings connected alternately with bolts. The disc sets are made of multiple layers of 0.2-0.6mm thick stainless steel sheets, and they are available in two common shapes: link-style and full-plate style, which are flexible to meet various transmission requirements. The all-metal structure design eliminates the use of non-metallic elastic components such as rubber or nylon, which are common in traditional couplings. This solution effectively addresses the issues of material aging, poor high and low-temperature resistance, and low corrosion resistance. The stainless steel discs provide excellent elastic deformation capability, effectively compensating for axial, radial, and angular misalignment, ensuring stable operation in high-precision applications.
With its compact design and high-performance transmission characteristics, the JMII series disc coupling is the ideal choice for industrial automation, machine tools, fans, pumps, and other equipment. It effectively enhances the stability and efficiency of the transmission system while reducing maintenance costs.
