Metal Bellows couplings GWB

Highly precise, torsionally stiff, and backlash-free, the world's leading metal bellows couplings of the GWB series—formerly known as GERWAH GWB—are ideal for applications where torques or rotary movements must be transmitted from shaft to shaft with the highest angular accuracy. These couplings are perfect for use in linear and spindle lifting units of machine tools and packaging machines, medical and pump technology, test benches, automation, conveyor and control technology, robotics, and more. Thanks to their characteristic stainless steel bellows, they effectively compensate for radial, axial, and angular shaft misalignments, ensuring precise positioning of the drive train at all times. All metal bellows couplings of the GWB series are wear- and maintenance-free, extremely easy to install, highly compact in design, and have a low moment of inertia. This allows users to achieve maximum cost-efficiency and operational reliability, whether they choose a proven standard design or a specially developed custom solution.
