What do you know about Bellows Couplings?

A bellows coupling is a type of flexible coupling that features high torsional stiffness, low moment of inertia, and minimal restoring forces under misalignment. These characteristics make bellows couplings suitable for motion systems that require a high degree of accuracy, repeatability.

Most bellows couplings use a stainless steel tube, which has been hydroformed to create deep corrugations that make them flexible across axial, angular, and parallel shaft misalignment, while maintaining its torsional rigidity. With no moving components, bellows couplings are low maintenance and have zero backlash.
