Metal bellows shaft couplings deliver, high torsional rigidity, due to the bellows’ radial rigidity and low side thrust due to the bellows lateral flexibility.

Other coupling types have either low windup or low side thrust, but not both. Precision motion control applications require mechanically tight systems, especially between motors, driven loads, and feedback devices, to ensure accurate positioning. Such systems often require shaft couplings that are both torsionally rigid, to accurately transmit rotational position and laterally flexible to accommodate shaft misalignment.

Key product advantages are

  • Backlash free operation
  • Torque range : 18 to 5000 Nm
  • Torsionally stiff
  • Maintenance free
  • To suit shaft sizes from 1mm to 100mm (H7)
  • Suitable for high temperatures from -30C to +120C
  • Corrosion resistant
