- Options: Isolated version (HKI 5)
Single joint couplings
Corrosion proof HK metal multiple disc couplings compensate an angular
offset up to 0.5° and an axial misalignment up to ±1 mm as well as
extending the service life of encoders in the process. Single 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.
