Description
HKI 97-112 up to 191
Double joint couplings
- For encoder attachments with increased offset (parallel/axial)
- Play-free, torsion resistant, failsafe and isolated
- Extends service life of encoders
- Options: Variety of attachment possibilities
Double joint couplings
The isolated and corrosion proof HKI metal multiple disc couplings compensate an increased parallel misalignment up to ±1 mm and an axial misalignment up to ±2 mm as well as extending the service life of encoders in the process. Double joint couplings are optionally available with attachment options for large bore diameters up to 40 mm as well as for shafts without a feather key (positive fit) or tapered shaft.
