HKD / HKDI 5… | Double joint coupling
Accessories – mechanical
- For encoder attachments with offset
- Play-free, torsion resistant and failsafe
- Extends service life of encoders
- Options: Isolated version (HKDI 5)
The stable connections
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.
