Double joint couplings
Corrosion proof HKD metal multiple disc couplings compensate a parallel
misalignment up to ±0.5 mm and an axial misalignment up to ±1 mm as well
as extending the service life of encoders in the process. Double joint
couplings are available with different hub lengths and bore diameters in
addition to isolated coupling versions for attachments where the risk
of shaft currents is a concern.
