All products are provided with hex socket set screws.
In a case where the bore diameter is φ 4 or less, the set screw is used in only one place.
Recommended dimensional allowances of applicable shaft diameter are h6 and h7.

Characteristics
- Applicable motors
MLR MLRS Servomotor ◎ ◎ Stepping motor ◎ ◎ General-purpose motor – – ◎：Excellent ○：Very good
- Property
MLR MLRS Zero Backlash ◎ ◎ High Torque ○ ○ High Torsional Stiffness ◎ ◎ Corrosion Resistance (All S.S.) – ◎ ◎：Excellent ○：Very good
- This is a long type rigid coupling.
- This can also be used as a joint for extending a shaft.
- There are two types of units made of aluminum alloy or stainless steel.
- There are clamping type and semi-split type.
Application
Cleaning equipment/Transport device
Selection
The area bounded by the shaft diameter and rated torque indicates is the selection size.
Selection example
In case of selected parameters of shaft diameter of φ10 and load torque of 4 N・m, the selected size is MLR-25C or MLR-25V.
Semi-split type
Semi-split type is an attachment method in which one side of the hubs is clamping type and the other side is split type.
While keeping one shaft attached on clamping side, the other shaft can be mounted or removed on split side, thus easier assembling set up.
