ARPEX All-Steel Coupling

High power density and resilience


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.

Sourced from our product partner, Flender.
