A Diaphragm Coupling is a high-performance flexible coupling that uses one or more metallic diaphragms (thin stainless steel plates) to transmit torque between shafts. It accommodates misalignment through elastic deformation of the diaphragms, while maintaining high torsional rigidity.
Unlike gear or elastomeric couplings, diaphragm couplings do not require lubrication and offer precise, backlash-free torque transmission, making them ideal for high-speed and high-precision applications.
