Top speed: 720 km/h

• Torsionally rigid, backlash-free, all-steel multiple-disk coupling for high-speed applications
• Nominal torque range from TKN = 1,000 Nm up to 588,500 Nm with 16 sizes
• Temperature range: from –40 °C to +280 °C

ARPEX ART® high performance couplings consist of pure expertise combined with the greatest possible power density. They are used in all high-speed drive systems that require torque transfer where shaft misalignment is occurring simultaneously. The ARPEX ART leaves nothing to be desired in terms of both bore capacity and safety: their compact design allows them to compensate for all of the expected misalignments in a very small space and, at the same time, gives them the highest possible torque capacity, the lowest possible weight and a very good center of gravity.

The double-cardan principle used in the ARPEX ART enables very high radial offsets, even under great loads. With thin, individual disks, the reaction forces that occur with shaft misalignments remain relatively low. The disks of the ARPEX ART high-performance coupling consist of high-alloyed stainless spring steel, and all of the other coupling components are made of high- quality, heat-treated steel.

One strength of the ARPEX ART is the achievable balance quality. This is the result of very high processing quality, extremely low production tolerances and high-precision assembly processes.
