EasyMech NEMA23 Aluminium Shaft Coupling 6.35x8mm

This EasyMech coupling is designed with bore diameters of 6.35mm and 8mm. This specific configuration allows for direct connection between shafts of these two distinct sizes, commonly found in NEMA23 stepper motors and lead screws or other driven components.

Yes, constructed from HE-30 grade aluminum, this coupling provides excellent strength for its size. When properly secured with the included grub screws, it offers a rigid connection suitable for transmitting moderate to high torque in most CNC, 3D printing, and automation applications without slippage.

The EasyMech shaft coupling is precisely machined from high-grade HE-30 aluminum metal alloy. This material choice ensures a balance of strength, lightweight properties, and resistance to corrosion, making it durable and reliable for long-term use in various mechanical environments.

The coupling is secured to the motor and driven shafts using two M4x6 socket set screws, also known as Allen grub screws. These screws are tightened against the shaft surfaces to create a friction fit. An Allen key is included for convenient and rigid installation.

While the bore sizes are fixed at 6.35mm and 8mm, this coupling is primarily optimized for NEMA23 stepper motors, which often feature a 6.35mm shaft. It can be used with any motor or shaft system that precisely matches these specified bore dimensions, ensuring proper fit and performance.
