TORSIONALLY RIGID ALL-STEEL COUPLINGS ARPEX ARW-4/-6 SERIES

DESCRIPTION: ARPEX couplings of the ARW-4/-6 series are outstanding for their large angular misalignment capacity of 3°. They were specially designed for drives where high misalignments which have to be compensated for by the coupling are to be expected. The intermediate spacer lengths are variable and are manufactured to customer specifications.

SPECIFICATIONS

TORSIONALLY RIGID ALL-STEEL COUPLINGS ARPEX ARW-4/-6 SERIES

- Nominal torque range from TNK = 92 Nm up to 80.000 Nm with 19 sizes

- Diameter (mm): from 101 mm to 880 mm

- Speed (rpm): from 10.400 to 1.150 rpm

- Arpex ARW couplings are composed of flexible steel discs designed to be bolted alternately between between the flanges of the coupling hubs and the intermediate spacer.

- Arpex ARW coupling has 2 series: 4 and 6

- Arpex ARW series 4 uses tetragonal discs (series includes ring discs)

- Arpex ARW series 6 uses hexagonal discs (series includes side-bar plates)

Benefits of the ARW Couplings

ARPEX couplings of the ARW-4/-6 series are used where large misalignment capacities are required. In the paper-making machine industry, the ARW coupling has already proved itself as a maintenance-free alternative to the Cardan shaft.
