4mm to 6mm Rigid Flange Coupling - Shaft Connector for Motors

4mm to 6mm Rigid Flange Coupling - Shaft Connector
✔️ Connects 4mm and 6mm Shafts - Solid Aluminum Flange Design

This rigid flange coupler allows you to securely connect a 4mm shaft to a 6mm shaft for accurate torque transmission. Ideal for stepper motors, small drive systems, or DIY mechanical projects, it provides a strong, backlash-free link between mismatched shaft sizes.

✅ Connects 4mm to 6mm diameter shafts
✅ Includes two flanges: one with 4mm bore, one with 6mm bore
✅ Cylindrical section diameter: 10mm
✅ Overall height: 12mm
✅ Bottom flange diameter: 22mm
✅ Fixing method: M3 screws
✅ Hole spacing: 16mm center-to-center
✅ Rigid coupling - no flexibility or compensation for misalignment

💡 When should you use a rigid flange coupler in a shaft connection?
They’re perfect for precise, solid torque transfer where alignment is well-controlled.

• Maintains exact rotational alignment between shafts

• Ideal for 3D printers, CNC motors, and sensor linkages

• No slip, no flex - full rotation transfer

• Compact design fits tight builds

Need to bridge two different shaft sizes with zero play? Add this flange coupler and keep your motion locked in step!
