- 🔧 BORE SIZES FROM 2MM TO 16MM – Available in 2mm, 3mm, 3.17mm, 4mm, 5mm, 6mm, 6.35mm, 7mm, 8mm, 10mm, 12mm, 14mm, and 16mm inner diameters to suit a wide range of motor shafts and guide rods. sizes like 3.17mm and 6.35mm match standard RC and stepper motor shafts without adapters .
- ⚙️ RIGID FLANGE MOUNTING DESIGN – The integrated circular flange base with mounting holes 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 transmission stable under load for precision linear motion setups .
- 🛡️ LIGHTWEIGHT ALUMINUM ALLOY BODY – Manufactured from high-quality aluminum alloy with an anodized or electroplated finish, offering excellent corrosion resistance and wear durability. The hardened construction maintains concentricity through repeated use while keeping weight minimal .
- 🔩 SECURE SET SCREW CLAMPING – Each coupler uses grub screws to lock onto the shaft securely. Smaller sizes (2-6mm) feature for M3 screws with 16mm diagonal spacing, while larger sizes use for M4 screws with 24-26mm spacing, providing 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 .
