Ringfeder GWB AK Metal Bellows Coupling
Product Name: Ringfeder GWB AK Metal Bellows Coupling
Product Brand: Ringfeder
Product Code: GWB AK
Product Artikel: Ringfeder GWB AK Metal Bellows Coupling
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

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.
