＊1： Correction of rated torque and max. torque due to load fluctuation is not required. For more detailed information, please refer to Selection Guidelines.
＊2： These are values with max. bore diameter.
Slip torqueConcerning the sizes shown in the table, please note that the shaft's slip torque is smaller than the rated torque of MBB-C.

Clamping TypeMBB-C Aluminum alloy hub
Head Cap Screw
- Applicable motors
- This is a bellows type flexible coupling.
- The bellows allows eccentricity, angular misalignment, and end-play.
- The bellows is stainless steel.
ApplicationActuator / High precision XY stage / Semiconductor devices / Encoder
Selection ExampleIn case of selected parameters of shaft diameter of φ10 and load torque of 2 N・m, the selected size for MBB is MBB-27C.
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 MBB 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.
