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.

Did you know?

In addition to our tried-and-tested MHM and BVB series, we offer others including the balance optimized series XVX. The arrangement of the coupling’s parts enables the lowest torque load on the connecting shafts. This series is outstanding for use in high-speed turbine drives with exacting requirements concerning the gravity position and the weight of the half coupling.
