GERWAH's 'PKN' unites the tried and tested technical advantages of a metal bellows coupling and a plug-in connection. These elements do not need any axial initial load due to tightening and thus allow for easy mounting and disassembly. The PKN series is the perfect choice when power has to be transmitted from shaft to shaft with the greatest possible angular accuracy. 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...
