- 🔧 MULTIPLE BORE SIZES AVAILABLE – Choose from 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 10mm, 11mm, or 12mm inner diameters to match your specific motor and guide shaft requirements. Common sizes like 3.17mm and 6.35mm are also available for shaft compatibility .
- ⚙️ RIGID FLANGE DESIGN FOR STABILITY – The rigid flange structure fixes one shaft to a flat surface, providing dual connection points that hold the coupler securely in place during operation. This design makes the shaft more stable and prevents separation under load .
- 🛡️ DURABLE STEEL CONSTRUCTION – Crafted from 45# carbon steel with heat treatment and electroplating, offering excellent strength and resistance to deformation under pressure. The robust build ensures long service life and reliable performance in demanding mechanical applications .
- 🔩 SECURE SET SCREW LOCKING – Each coupling includes set screws to firmly clamp onto the shaft. Smaller sizes (3-6mm) use for M3 screws with 16mm diagonal hole spacing, while larger sizes (7-12mm) use for M4 screws with 24-26mm spacing for a secure fit .
- 🚲 VERSATILE DIY APPLICATION – Widely used in 3D printers, CNC machines, RC model motors, stepper motors, and DIY robotics projects. Perfect for connecting motor shafts to lead screws or guide shafts where precise alignment and rigid power transmission are required .
