Siemens SIPEX


SIPEX couplings are made up of two aluminium hubs and stainless steel bellows. Their metal bellows compensate for axial, radial and angular misalignment with only low restoring forces. They cover a torque range from 0.5 to 5,000 Nm.

SIPEX Couplings are almost completely maintenance and wear-free with an exceedingly low moment of inertia. They are very compact, suitable for a range of installation requirements due to availability of different hub versions and very easy to install.
