Metal Bellows Couplings

Highly precise, torsionally stiff, backlash-free – the world’s leading metal bellows couplings of the RINGFEDER® GWB series – formerly GERWAH® GWB – are ideal for all applications in which torques or rotary movements must be transmitted from shaft to shaft with highest angular accuracy: In linear and spindle lifting units of machine tools and packaging machines, in medical and pump technology, in test benches, in automation, conveyor and control technology, in robotics and much more. Thanks to the characteristic metal bellow made of stainless steel, they compensate for radial, axial and angular shaft misalignments highly effectively, thus ensuring that the drive train is always positioned precisely. All metal bellows couplings of the RINGFEDER® GWB series are wear- and maintenance-free, extremely easy to install, highly compact in design and have a low moment of inertia. Users can thus achieve maximum cost-efficiency and operational reliability in equal measure – regardless of whether they use a proven standard design or a specially developed custom design.
