Metal Bellows Couplings

Metal bellows couplings are the premier choice for applications demanding high dynamic positioning, making them ideal for servo drives. They provide an entirely backlash-free operation and exceptional torsional rigidity. With maintenance-free performance, outstanding fatigue resistance, and minimal restoring forces even under misalignment, these couplings deliver reliability and precision. Our modular system offers unparalleled versatility, ensuring the perfect coupling solution for every assembly requirement.
