Metal bellows couplings from the 'AK' series have been designed especially for the backlash-free transmission of high torques of up to 5,000 Nm. The elements are mounted on driver and driven components with tapered clamping bushings. Depending on the required size, the coupling will be produced with hubs made of aluminum or stainless steel. In addition, AK guarantees for perfect concentric running. Characteristics Backlash-free transmission of torque High torsional stiffness, precision of transmission of rotational angle Different torsional stiffness Compact design, low moment of inertia Metal bellows made of stainless steel Simple and safe assembly Compensation of radial, axial and angular misalignment Free of wear, maintenance-free, no downtimes Not sensitive to temperatures between -30°C and + 100°C Nominal torques between 0,1 – 5000 Nm Advantages 100% inspection and traceability through individual marking Higher torques at same dimensions Compact design Extended bore ranges Customer-specific solutions Higher safety in application, e.g. no wrong screw tightening torques Backlash-free Metal Bellows Couplings are used in the sector of mechanical engineering, where a torque or a rotary motion has to be transmitted from shaft to shaft in highest accuracy of angle.
