DMB Type Key Connection Single Type Elastic Diaphragm Coupling (Q/YP 22004X-2018) is a high-performance metal elastic transmission component designed for precision torque transfer systems. It adopts a single diaphragm structure combined with a key connection design, enabling reliable torque transmission while effectively compensating for axial, angular, and limited radial misalignments through the elastic deformation of high-strength metal diaphragms. This structure ensures high torsional rigidity and stable dynamic performance under high-speed operating conditions.
With its compact structure, zero-backlash transmission characteristics, and lubrication-free operation, the DMB coupling is widely suitable for industrial fields requiring high precision and reliability, such as servo systems, precision machinery, metallurgical equipment, and power transmission systems. Its robust design improves operational stability while reducing maintenance requirements and enhancing long-term service life.
