SFC-025DA2-8B-14B-L29
Metal Disc Couplings SERVOFLEX SFC Series
Applications
NC lathe, machining center, chip mounter, actuator, SCARA robot, semiconductor manufacturing equipment
| Max. rated torque | [N·m] | 250 |
| Bore ranges | [mm] | Φ 3~45 |
High Stiffness and Ultra-low Inertia
Small- and medium-capacity model, which is made of a high-strength aluminum alloy and whose outer hub diameter is linked to the shaft diameter to achieve a ultra-low inertia ideal for high-speed rotation. Three different shapes are available depending on the combination of bore diameters you use.
Simple and Reliable Connection
A single clamping method is used for connection to the shaft. The clamping hub is shock and vibration proof, enabling reliable connection and helping to substantially reduce mounting time. A special jig is used for centering to achieve an extremely high concentricity.
Wide Variety of Options
A wide variety of options such as a tapered shaft, length-specified special order, and keyway milling application are available. You can combine options to meet your desired specifications.
＊1 For surface processing of the clamping bolts , black coating is applied only for #002.
＊2 The collar material in the marked area is S45C in sizes #080 to #100, and the surface finishing is trivalent chrome treatment.
＊3 The bolt surface finishing in the marked area is anti-rust coating in sizes #080 to #100.

* Types A / B / C are automatically specified by Miki Pulley according to the combination of bore diameters you select, and cannot be specified by the customer. * Check the Standard Bore Diameter list as rated torque may be restricted by the holding power of the shaft connection component. * Max. rotation speed does not take into account dynamic balance. * Torsional stiffness values given are measured values for the element alone. * The moment of inertia and mass are measured for the maximum bore diameter.

* 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 +0.010 -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. Consult Miki Pulley regarding special arrangements which may be possible for other bore diameters. * Bore diameters whose fields contain numbers are restricted in their rated torque by the holding power of the shaft connection component because the bore diameter is small. The numbers indicate the rated torque [N•m].

* Types A / B / C are automatically specified by Miki Pulley according to the combination of bore diameters you select, and cannot be specified by the customer. * The nominal diameter for the clamping bolt M is equal to the quantity minus the nominal diameter of the screw threads, where the quantity is for a hub on one side. * The figures in parentheses ( ) for the SFC-010 are the values when d1 or d2 is ø8 mm. * Compatible lengths L range from the minimum L dimension to the maximum L dimension shown in the above table. Specify in 1 mm units. * When the L dimension is shorter than the standard, the left/right clamping bolt phases will be off by 45°. * Check "Standard Bore Diameters" for SFC (DA2) for the standard bore diameters.

* 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 +0.010 -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. Consult Miki Pulley regarding special arrangements which may be possible for other bore diameters. * Bore diameters whose fields contain numbers are restricted in their rated torque by the holding power of the shaft connection component because the bore diameter is small. The numbers indicate the rated torque [N•m].

* 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 +0.010 -0.025. * Bore diameters marked with ● or numbers are supported as the standard bore diameters. Consult Miki Pulley regarding special arrangements which may be possible for other bore diameters. * Bore diameters whose fields contain numbers are restricted in their rated torque by the holding power of the shaft connection component because the bore diameter is small. The numbers indicate the rated torque [N•m].
