The classic design of an ARPEX couplings of the ARS-6 series is shown in the following illustration. The plate packs are bolted alternately between the flanges of the coupling hubs and the intermediate spacer. Up to size 280-6 close-fitting bolts and from size 305-6 conical screw connections are used for fastening. A large number of intermediate spacer and shafts, hubs and flanges can be combined and thus cover a large number of possible drive requirements.

Variants of the ARPEX coupling, ARS-6 series

All coupling types can be very easily combined with further standard components in the ARPEX modular system. Jumbo hubs are used to permit larger maximum bores.
Clamping hubs transmit torque by friction without the use of parallel keys. F, D and C flanges offer many different possibilities for flange connection.

The coupling parts of the ARPEX ARS-6 series are machined on all sides. Exceptions are H and Z spacers and intermediate shafts. The spacers are delivered with unmachined, primed spacer tube.

Higher torques and maximum speeds with similar coupling outer diameters DA can be achieved with the ARPEX ARC-8/-10 series.
