ARPEX all-steel multi-disk couplings have proved themselves in drive technology for decades; they are used wherever a reliable, low-maintenance and above all precise torque transmission is required in cases of shaft misalignment.Torque is transmitted by torsionally rigid, flexurally elastic disks joined together by sleeves and rings to form a disk pack. Versions with two disk packs enable not only angular and axial but also radial shaft misalignments to be compensated for.
ARPEX all-steel multi-disk couplings are free of circumferential backlash, are compact in design and stand out for their low power-to-weight ratio. On the new N-ARPEX these qualities are brought to perfection. Its special torque capacity and its high speed potential make the N-ARPEX the best-performing all-steel multi-disk coupling in the market at present. And with its API conformance and ATEX certification it is extremely fit for use. It is not only suitable for high but also for particularly low ambient temperatures down to -50 °C. Thanks to its low weight, its high performance and low complexity the N-ARPEX saves on investment and life-cycle costs. The range of modular components for ARPEX all-steel multi-disk couplings offers many different possible configurations for applications up to 1,450,000 Nm.
