They are preferred in applications where the focus lies on pure torque and power transmission. The choice of three coupling spiders with different hardness values allows the properties of the coupling to be optimally matched to the spe- cific requirements. The clamping hubs and simple plug-in installation make jaw couplings very easy to assemble. With the bore code K, the keyway is always integrated into both bores d 2 and d 3 . see also... • Assembly Instructions on Couplings → Page 1694 • Technical Information on Couplings → Page 1696 • Elastomer Jaw Couplings GN 2241 (with Grub Screw) → Page 1682 • Oldham Couplings GN 2242 (with Clamping Hub) → Page 1684 Information 1 d 1 2 Bore code 3 d 2 - d 3 4 Material 5 Hardness How to order 1 2 3 4 5 GN2240-40-B12-16-AL-RS • Hub Aluminum AL Anodized, natural color • Coupling spider Polyurethane (TPU) - - Temperature resistant up to 60 °C - - Hardness 80 Shore A, blue BS 92 Shore A, white WS 98 Shore A, red RS • Socket cap screws DIN 912 Steel, blackened • Temperature range: -20 °C up to +60 °C • Keyway P9 DIN 6885 → Page 2078 • ISO Fundamental Tolerances → Page 2151 • Elastomer Characteristics → Page 2158 • RoHS • Coupling Spiders GN 2240.1 → Page 1692 Accessory Specification 4 5 d 1 Coupling spider Shore hardness coupling spider Rated torque in Nm Max. 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 ° 14 BS 80A  0,7   1,4 45.000 2,0 x 10⁻⁷   8 0,15 0,6 1 WS 92A  1,2   2,4 45.000 2,0 x 10⁻⁷  14 0,1 0,6 1 RS 98A  2   4 45.000 2,0 x 10⁻⁷  22 0,1 0,6 1 20 BS 80A  1,8   3,6 31.000 1,1 x 10⁻⁶  16 0,2 0,8 1 WS 92A  3   6 31.000 1,1 x 10⁻⁶  29 0,15 0,8 1 RS 98A  5  10 31.000 1,1 x 10⁻⁶  55 0,1 0,8 1 30 BS 80A  4   8 21.000 6,2 x 10⁻⁶  46 0,2 1 1 WS 92A  7,5  15 21.000 6,2 x 10⁻⁶  73 0,15 1 1 RS 98A 12,5  25 21.000 6,2 x 10⁻⁶ 130 0,1 1 1 40 BS 80A  4,9   9,8 15.000 3,7 x 10⁻⁵ 380 0,15 1,2 1 WS 92A 10  20 15.000 3,7 x 10⁻⁵ 570 0,1 1,2 1 RS 98A 17  34 15.000 3,7 x 10⁻⁵ 1200 0,1 1,2 1 55 BS 80A 17  34 11.000 1,6 x 10⁻⁴ 1400 0,2 1,4 1 WS 92A 35  70 11.000 1,6 x 10⁻⁴ 1600 0,15 1,4 1 RS 98A 60 120 11.000 1,6 x 10⁻⁴ 2600 0,1 1,4 1 GN 2240 Elastomer Jaw Couplings continued
