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.

- Property
MRG MRGS Zero Backlash ◎ ◎ High Torque ◎ ○ High Torsional Stiffness ◎ ◎ Corrosion Resistance (All S.S.) – ◎ ◎:Excellent ○:Very good
- These are rigid-type couplings.
- Light weight and ultra small moment of inertia. High response.
- There are two types of units made of aluminum alloy or all stainless steel.
- There are three attachment methods: set screw type, clamping type, and split type.
- Sizes of φ40 – φ65 in outside diameter have been added.
Application
High precision XY stage/Machine tool/Cleaning equipment
Selection
The area bounded by the shaft diameter and rated torque indicates is the selection size.
