Rigid Flange Coupling 3-14mm Motor Guide Shaft Coupler Connector(3mm)

Farbe: 3mm
Marke: ERYTRJF
Größe: One Size
Hersteller: ERYTRJF

- 🔧 BORE SIZES FROM 3MM TO 14MM – Available in 3mm, 3.17mm, 4mm, 5mm, 6mm, 6.35mm, 7mm, 8mm, 10mm, 11mm, 12mm, and 14mm inner diameters to suit a wide range of motor shafts and guide rods. The 3.17mm and 6.35mm options match standard RC and stepper motor shafts without adapters .
- ⚙️ RIGID FLANGE MOUNTING PLATE – The integrated flange base allows the coupler to be bolted to a flat surface, creating a fixed support point that prevents shaft wobble and axial drift during rotation. This dual-anchor design keeps the transmission stable under load, ideal for precision linear motion setups .
- 🛡️ HARDENED CARBON STEEL BODY – Manufactured from 45# carbon steel with heat treatment and electroplated surface, delivering high torsional rigidity and resistance to wear or deformation. The hardened construction maintains concentricity through repeated use in demanding mechanical assemblies .
- 🔩 SET SCREW SHAFT CLAMPING – Each coupler uses grub screws to lock onto the shaft securely. Sizes 3-6mm feature for M3 screws with 16mm diagonal spacing, while 7-14mm sizes use for M4 screws with 24-26mm spacing, providing a firm grip without marring the shaft surface .
- 🚲 WIDE DIY COMPATIBILITY – Suitable for 3D printer lead screws, CNC router axes, stepper motor shafts, RC model drivetrains, and robotics projects. Ideal wherever a rigid, low-backlash connection between motor and driven shaft is required .
