They are manufactured of a single piece and offer high torsional stiffness thanks to the alternating slits. The clam- ping hubs make beam couplings very easy to assemble. They are used in applications where precise position and movement transmission is required, such as in the drive systems of position measu- ring systems and in test benches. The stainless steel version can also be used in environments requiring high corrosion resistance, such as in medical technology (CAT scanners) and food-processing equipment (confectionary machines). see also... • Assembly Instructions on Couplings → Page 1694 • Technical Information on Couplings → Page 1696 • Bellows Couplings GN 2244 → Page 1688 • Elastomer Jaw Couplings GN 2240 (with Clamping Hub) → Page 1680 Information • Aluminum AL - - Anodized, natural color - - Temperature resistant up to 150 °C - - Socket cap screws DIN 912 Steel, blackened • Stainless steel AISI 303 NI - - Temperature resistant up to 200 °C - - Socket cap screws DIN 912 Stainless steel AISI 304Cu • ISO Fundamental Tolerances → Page 2151 • Stainless Steel Characteristics → Page 2166 • RoHS Specification 4 • Bore with keyway On request Aluminum d 1 Rated torque in Nm Max. speed (min ⁻ ¹) Moment of inertia in kgm² Static torsional stiffness in Nm/rad Max. shaft misalignment Lateral in mm Axial in mm Angular in ° 12 0,4 52.000 7,8 x 10⁻⁸  45 0,1 ± 0,3 2 16 0,5 39.000 3,4 x 10⁻⁷  80 0,1 ± 0,4 2 20 1 31.000 9,1 x 10⁻⁷ 170 0,1 ± 0,4 2 25 2 25.000 2,6 x 10⁻⁶ 380 0,15 ± 0,5 2 32 4 19.000 9,7 x 10⁻⁶ 500 0,15 ± 0,5 2 Stainless steel d 1 Rated torque in Nm Max. speed (min ⁻ ¹) Moment of inertia in kgm² Static torsional stiffness in Nm/rad Max. shaft misalignment Lateral in mm Axial in mm Angular in ° 12 0,3 52.000 2,2 x 10⁻⁷  64 0,1 ± 0,2 2 16 0,5 39.000 9,0 x 10⁻⁷  85 0,1 ± 0,3 2 20 1 31.000 2,5 x 10⁻⁶ 250 0,1 ± 0,3 2 25 2 25.000 7,1 x 10⁻⁶ 330 0,15 ± 0,4 2 32 3,5 19.000 2,7 x 10⁻⁵ 850 0,15 ± 0,5 2 1 d 1 2 Bore code 3 d 2  - d 3 4 Material How to order 1 2 3 4 GN2246-32-B 10-12-AL
