Motor specifications are based on general values.For details, see the motor manufacturer's catalogs.This is the size for cases where devices such as reduction gears are not used.

Selection Example

In case of motor specification of shaft diameter of φ14 and rated torque of 0.64 N•m, the selected size of MJC-**-BL is as follows.
Set Screw Type ----MJC-30-BL
Clamping Type ----MJC-30CS-BL
Set Screw + Key Type ----MJC-30K-BL
Clamping + Key Type ----MJC-30CSK-BL

Tight Fit

The hub and sleeve are press-fit and can be used under zero backlash*1.Since the sleeve's vibration absorption can raise the gain of a servomotor, this unit can achieve high responsive operation exceeding the Disk coupling.

*1: For the torque used under zero backlash, please refer to dimensional table.


Easy Fit

This unit allows you to easily assemble and partition the hub and sleeve. This allows you to reduce the time of assembling the unit and maintenance.It is possible to mount a hub on the shaft in advance and easily assemble the unit even in a location where the coupling is less-visible.

This is a value under the condition where the static torsional stiffness at 20°C is 100%.
The change of torsional stiffness within the range of allowable operating temperature is as shown in the graph.
Before using the unit, be aware of the deterioration of responsiveness.
