Metal Bellows Couplings GWB AKN | RINGFEDER®

The metal bellows couplings from the 'AKN' series boast trusted quality and increased torsional stiffness. The reduced shafts in the element guarantee for high stiffness while at the same time compensating angular, axial and radial misalignments. The shaft connection is established by means of clamping hubs on both sides.

Dimensions Dimensions

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.

  • Pumps with axial and vertical drives
  • High dynamic portal drives
  • Spindle lifting units
  • Linear units
  • Packaging machines
  • Machine tools
  • Special machines

Series AKN

  • Metal bellows coupling with clamping hubs, short length and higher torsional stiffness

Characteristics

  • Metal bellows made of stainless steel, hubs made of aluminum
  • The shaft tolerance should be within the fit tolerance “g6” or “h7”
  • The contact surfaces have to be free from oil and grease
  • Optional designs with keyway DIN 6885-1
  • Optional special design in stainless steel
