Usage
This coupling is versatile across a range of applications. It is perfect for hobbyist robotics, small‑scale CNC machines, automotive prototyping, and educational kits where reliable power transmission is essential. The coupler accommodates shaft diameters from 2 mm up to 6 mm, allowing it to bridge mismatched shafts commonly found in DIY projects and low‑volume manufacturing. Its flexible nature absorbs vibration and minor angular offsets, making it suitable for environments with dynamic loads, such as mobile robots navigating uneven terrain or test rigs that experience frequent start‑stop cycles. The included hex wrench and screws simplify the mounting process, enabling users to secure the coupling without additional tools.

FAQ
What shaft sizes does this coupling support?
The coupling is designed for inner diameters ranging from 2 mm to 6 mm, covering most small‑scale motor and wheel shafts used in robotics and prototyping.
Is the brass material suitable for high‑temperature environments?
Yes, brass maintains its structural integrity and dimensional stability up to approximately 200 °C, making it appropriate for many industrial and automotive applications.
Can I use this coupling with a shaft that has a slight oval shape?
The flexible nature of the coupling can accommodate minor ovalities, but for best performance we recommend using a perfectly round shaft to ensure even load distribution.
Do I need any additional tools to install the coupling?
No additional tools are required. The package includes a hex wrench that matches the screw heads, allowing you to secure the coupling quickly and securely.
What warranty or after‑sales service is offered?
MECCANIXITY provides a 12‑month warranty covering manufacturing defects, and our support team is available to assist with installation guidance or part replacements.
