※ The selected shaft's slip torque is smaller than the coupling's rated torque. Please note.
＊1： Correction of rated torque due to load fluctuation is not required. For more detailed information, please refer to Selection Guidelines.
Slip torqueAs in the table below, the clamping type MFBS-C has different slip torque according to the bore diameter. Take care during selection.

- This is a bellows type flexible coupling.
- The bellows allows eccentricity, angular misalignment, and end-play.
- Even if there is misalignment, the constant revolution is performed.
- There are two types of bellows: phosphor bronze type and stainless steel type.
Precautions for UseIn case of mounting on D-cut shaft, be careful about the position of the D-cut surface of the shaft. ⇒Mounting and Maintenance
There are sizes where the hex socket head bolt exceeds the outer diameter of the coupling and the rotating diameter is larger than the outer diameter. Please be careful of the interference of coupling.
Selection Based on Shaft Diameter and Rated TorqueThe area bounded by the shaft diameter and rated torque indicates the selection size.
Selection ExampleIn case of selected parameters of shaft diameter of φ10 and load torque of 2 N・m, the selected size forMFBMFB-32.
Eccentric Reaction Force
Thrust reaction force
Change in static torsional stiffness due to temperatureThis is a value under the condition where the static torsional stiffness at 20°C is 100%.
The change of MFB and MFBS in torsional stiffness due to temperature is small and the change in responsiveness is extremely small. If the unit is used under higher temperature, be careful about misalignment due to elongation or deflection of the shaft associated with thermal expansion.
