SFC [L] Fixed-Length Type
ダブルエレメントタイプの全長を対応範囲において1mm単位でご指定いただけます。中間に配置したスペーサの寸法を変更することで駆動－従動間に必要な寸法に対応します。また、スペーサ長さを変更することで、許容偏心量を大きくすることができ、よりフレキシブルな運転が可能です。

- *Please note that the shape type (A, B, or C) is automatically determined based on the combination of hole diameters you select, so you cannot specify it.
- *Please note that the allowable torque may be limited by the holding force of the shaft fastening section; please verify this using the standard bore diameter of the SFC (DA2).
- *The maximum rotational speed does not take dynamic balance into account.
- *The moment of inertia and mass are based on the maximum bore diameter.
- *Please refer to the SFC(DA2) specifications for the values of each spring constant.

- *Please note that the shape type (A, B, or C) is automatically determined based on the combination of hole diameters you select, so you cannot specify it.
- *The designation for Clamp Bolt M is based on the quantity and thread size; the quantity refers to the number of bolts on one side of the hub.
- *The values in parentheses for SFC-010 apply when d1 or d2 is 8 mm.
- *The total length L that can be accommodated is the range from the minimum to the maximum L dimension shown in the table above. Please specify the length in 1-mm increments.
- *If the L dimension is shorter than the standard, the left and right clamp bolts will be offset by 45°.
- *Please refer to the standard bore diameter for SFC (DA2).
