Compact coupling HK

shaft-hubshaftwith encoder

For encoder attachments with small offset, e.g. flange mountings Play-free, torsion resistant and failsafe Extended lifetime of encoders Option: isolated version Description The corrosion-resistant HK metal multiple disc couplings compensate for an angular misalignment of up to 0.5° and an axial misalignment of up to ±1 mm, thus extending the service life of encoders. The single-jointed couplings are available with different hub lengths and bore diameters as well as insulated couplings for attachments with shaft current hazard. Technical data Application Compensation axial misalignment Compensation angular offset Isolation against existing bearing/shaft currents Mounting accuracy Angular offset: up to 0.5° / axial misalignment: up to ±1 mm Bore drive side max.
