METAL DISC COUPLINGS SERVOFLEX SFC SA2 – Datasheet SINGLE ELEMENT TYPE ■ Specifications Model Shape type Torsional stiffness [N·m/rad] • The rated torque of the coupling may be limited for bore diameters. • Higher rpm possible with balancing. • Torsional stiffness values given are measured values for the flexible element alone. • The moment of inertia and mass are specified for the maximum bore diameter. Shape type M Quantity – Tightening torque Nominal dia. [N·m] • øDB = Interference radius of the screw head • The figures in parentheses ( ) for

■ Standard Bore Diameter Standard (option) bore diameter, d1/d2 [mm] and related rated torque [N·m] 3 Shaft tolerance Nominal bore diameter Supported bore diameter for each model ＋ 0.010 • The shaft tolerance for standard bore diameter is h7 (h6 or g6): designation B. However, for a bore diameter of ø35, the shaft tolerance is － 0.025. • Shaft tolerances j6/k6: designations J/K are optional, and are only supported for bore diameters marked with ○ . • Bore diameters marked with ● or numbers are supported as the standard bore diameters.
