| Special features and certificates | |
| The stable connections | |
| 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. | |
