The best-performing coupling on the market

• Backlash-free, torsionally rigid all-steel multi-disk coupling
• Nominal torque range from TKN = 350 Nm to 2,000,000 Nm
• Temperature range: from –50 °C to +280 °C

Investment costs, lifecycle costs, power-to-weight ratio, fitness for use and the cost of purchasing couplings are key considerations for equipment manufacturers.

With the introduction of the new N-ARPEX® all-steel multi-disk coupling Flender is continuing the success story of the proven ARPEX® series of couplings. The N-ARPEX is currently the most powerful coupling on the market due to the consistent further development of the ARPEX – a leap in performance that in this size could only be achieved by means of various design features. With the N-ARPEX, Flender delivers the optimum price-performance ratio.

With our all-steel couplings, the reliable transmission of torque between the shafts to be connected is backlash-free, torsionally rigid and flexurally elastic. This enables them to compensate for axial, angular and radial misalignment. Our multi-disk couplings are not prone to wear and are maintenance-free.

The couplings have been designed for use in potentially explosive environments as defined in Directive 2014/34/EU (ATEX) and comply with the requirements in standards
API 610 and API 671.
