- The shape TYPE (A, B, C) is automatically determined based on the combination of hole diameters you select, so you cannot specify it.
- The allowable torque may be limited by the holding force of the fastener section, so please check with the standard bore diameter. The maximum rotating speed does not take dynamic balance into consideration.
- The value of the torsion spring constant is the measured value for the element section only.
- The moment of inertia and the weight are values at maximum bore diameter.

- The shape TYPE (A, B, C) is automatically determined based on the combination of hole diameters you select, so you cannot specify it.
- The ⌀DB dimension is the dimension when the head of the clamp bolt protrudes beyond the hub outer diameter.
- The K dimension is the element inner diameter. If the d2 dimension exceeds this value, the shaft can only be inserted into the d2 side hub up to the LF dimension.
- The nominal of clamp bolt M is the quantity-nominal thread size, and the quantity is for one side hub.
- The values in parentheses for SFC-010 apply when d1 or d2 is ⌀8 mm.
