Unique-Bargains 11mm Rigid Flange Coupling Silver 2PCS
Two rigid aluminium-alloy flange couplings with 11 mm bore, 13 mm height and 18 mm outer diameter for RC motor shafts
- 11 mm bore fits standard motor shafts
- Aluminium alloy body resists corrosion
- Rigid flange design keeps alignment true
- 26 mm hole spacing simplifies mounting
- Pack includes two couplers and four screws
11 mm Rigid Flange Coupling Pair
This two-piece set provides a solid aluminium-alloy link between an 11 mm motor shaft and a driven component. The flange design uses four M4 mounting holes on a 26 mm bolt circle for secure attachment in RC models and light mechanical drives.
Suits hobbyists joining 11 mm shafts.
Builders working with 11 mm motor shafts on aircraft, boats or DIY projects will find the rigid connection eliminates backlash. Anyone needing flexible misalignment compensation, keyed shafts or diameters other than 11 mm should select a different coupling style.
Handles light torque in small-scale drives.
The 18 mm outer cylinder and 32 mm base flange transmit torque cleanly while the 13 mm overall height keeps the assembly compact. Because the coupling is completely rigid it cannot absorb angular or parallel misalignment, so precise shaft alignment is essential to avoid binding or premature wear.
Highlights
- 11 mm bore fits standard motor shafts
- Aluminium alloy body resists corrosion
- Rigid flange design keeps alignment true
- 26 mm hole spacing simplifies mounting
- Pack includes two couplers and four screws

Questions about this item
What shaft diameter must I already have for the 11mm inner diameter to fit?
The coupling accepts an 11mm shaft, so the motor or guide shaft you are connecting must measure 11mm at the mounting point.
Will the 26mm mounting-hole spacing line up with the bolt pattern on my existing motor mount?
The flange has four holes on a 26mm pitch circle; compare that dimension to your current mount before ordering.
How can I confirm the coupling is seated correctly after tightening the four included screws?
With the screws secured, the shaft should turn freely without wobble and the 13mm overall height should sit flush against the mounting surface.
