6 MM Shaft BO Motor Coupling

6mm Shaft BO Motor Coupling – Shaft Adaptor for BO Motors

The motor coupling shaft in this adapter is engineered to convert a BO motor’s flat output into a universal 6mm round format. This ensures smooth compatibility with wheels, gears, and pulleys, while also supporting setups that require both a servo to shaft coupler or a reliable coupling wheel. Because it fits securely and installs easily, the motor coupling shaft is widely used in DIY robotics and classroom automation builds. By offering stable rotation and consistent torque transfer, this  coupling shaft helps makers align wheels or gears more precisely. It also allows users to integrate accessories that normally require a servo to shaft coupler or similar connector. Additionally, the design supports projects where a coupling wheel needs firm and vibration-free attachment. Durable, lightweight, and simple to mount, this motor coupling shaft adapter is ideal for student kits and mechanical prototypes. Even in compact robot frames, it allows easy pairing with wheel hubs, especially when switching between attachments such as a servo to shaft coupler or a custom coupling wheel assembly. Overall, the motor coupling shaft ensures stable performance in both educational and hobby-grade robotic systems.
