The CMU Hex Shaft Coupling 18MMX4MM is a compact and reliable mechanical connector designed to securely link a DC gear motor shaft to a wheel or hub. With a 4mm internal diameter and 18mm overall length, this coupling ensures efficient torque transmission while maintaining stable and accurate alignment between connected components.
Manufactured from high-quality brass, the coupling offers excellent strength, corrosion resistance, and long-term durability. Brass construction also provides smooth engagement with motor shafts, reducing wear and minimizing vibration during operation. The hex-style design enhances grip and helps prevent slippage under load, making it ideal for robotics, small vehicles, and DIY motion-control projects.
This shaft coupling is supplied with two securing screws (M3×6 and M4×8), allowing for firm and adjustable fastening to different shaft and wheel configurations. Installation is quick and straightforward, requiring only basic hand tools. Once secured, the coupling provides a stable mechanical connection suitable for continuous operation.
