6mm Flanged Coupling – Aluminum Motor Shaft Mounting Hub

6mm Flanged Coupling for DC Motor Shafts

Product Description

The 6mm Flanged Coupling is a lightweight and durable mechanical component designed to connect a standard 6mm motor shaft to external mechanisms such as wheels, gears, cranks, pulleys, robotic arms, and custom 3D-printed parts.

Made from aluminium, the coupling provides a rigid connection between the motor and attached mechanism while keeping weight and rotational inertia low. Its flanged design offers a convenient mounting surface for custom mechanical components.

Rigid Mechanical Connection

The coupling is designed to securely transfer rotational motion from the motor shaft to the attached mechanism. A rigid connection helps minimize unwanted play or movement, making it suitable for robotics and precision mechanical applications.

Versatile Flanged Design

The flat flange provides a convenient surface for attaching links, gears, wheels, cranks, and custom brackets using suitable screws or fasteners. This makes the coupling useful for both prototype and finished mechanical assemblies.
