Siemens ARPEX Disc Couplings

ARPEX all-steel couplings are free of backlash, have a compact design and are characterized by a low power-to weight ratio. They are suitable for use at high ambient temperatures and particularly for machines that must be driven precisely, e.g. paper and printing machines, pumps, compressors and high-speed generators.

With numerous standard components, ARPEX couplings can be combined into a wide variety of designs that can be used in many applications. The product range includes eight different series with performance ranges from 92 Nm to 1,450,000 Nm.
