Overview
ARPEX couplings have proved themselves for over 30 years in all areas of technology where reliable, maintenance-free torque transmission is required. ARPEX couplings link machine shafts and compensate for shaft misalignments, while generating only low restorative forces. Thanks to the use of spring steel plates and backlash-free screw connections, ARPEX couplings are torsionally rigid and backlash-free. All ARPEX coupling components are manufactured from high-quality steel. Robust, compact construction guaranteeing a high level of operational reliability and a long service life is therefore possible. High-precision production ensures that at speed in the assembled condition only low forces act on the machine parts connected to them. ARPEX couplings can be used for both directions of rotation and are thus also suitable for reverse operation.

ARPEX couplings are not subject to wear and, if correctly designed, assembled and installed, can be expected to have an unlimited service life. With most types the intermediate spacer can be fitted radially without having to move the driving and driven machines.

Thanks to a large number of standard components ARPEX couplings can be combined to make many different types. In this way, standard types can be used with many drives.

ARPEX couplings can withstand temperatures between –40 °C and +280 °C in operation. On request, they can also be specially equipped for use in other temperature ranges.

To meet the high quality demands made of ARPEX couplings, the development and manufacture of ARPEX couplings is integrated into a certified quality management system in accordance with the requirements of DIN EN ISO 9001.

Type approval for use of ARPEX couplings in shipbuilding has been issued by the following classification societies: American Bureau of Shipping (ABS), Det Norske Veritas (DNV), Germanischer Lloyd (GL) and Lloyd's Register of Shipping. Product certification to GOST-R for the Russian market has already been obtained.
