Ambient temperature Temperature correction factor for GN 2240 / GN 2241 for GN 2242 / GN 2243 -20 °C up to +30 °C 1 1 +30 °C up to +40 °C 0,8 0,8 +40 °C up to +60 °C 0,7 0,7 +60 °C up to +80 °C - 0,55 Static torsional stiffness and temperature The diagrams show the change in static torsional stiffness within the permissible operating temperature range, under the assumption that the static torsional stiffness at 20 °C is 100 percent. The torsional stiffness of the couplings decreases with increasing temperature. GN 2240 / GN 2241
