Metal Bellows Couplings GWB
Our Metal Bellows Couplings of the RINGFEDER® GWB series – originating from the proven GERWAH® GWB product line – stand for absolute freedom from backlash, maximum angular accuracy and outstanding dynamic performance in demanding drive systems. They are particularly suitable for applications in which torques and motions must be transmitted with the highest precision, for example in machine tools, packaging machinery, linear units, screw jack systems, pump drives, test rigs, as well as automation, control and positioning systems. The torsionally rigid couplings transmit torque wear- and maintenance-free via a high-quality metal bellows made of stainless steel while simultaneously compensating for radial, axial and angular shaft misalignments. Thanks to their high torsional stiffness, compact dimensions and low moments of inertia, they enable highly dynamic motion sequences with precise positioning. Furthermore, the extensive modular design system with numerous hub, mounting and special configurations provides optimal conditions for application-specific drive solutions.
