6mm Axle Shaft for Robot-8 Inches

6mm Robotics Axle Shaft with M3 Threaded Ends

Product Description

The 6mm Robotics Axle Shaft is a durable metal shaft designed for building robot chassis, idler wheels, extended axles, custom gearboxes, and mechanical linkages. Its standard 6mm diameter makes it compatible with common 6mm bearings, wheels, couplings, gears, and motor mounts.

Unlike plain smooth shafts, this axle features M3 threaded holes on both ends, allowing wheels, pulleys, and other components to be secured using screws and washers.

Secure Wheel Mounting

The M3 tapped holes provide a simple and reliable method for retaining wheels and pulleys on the shaft. This helps prevent components from slipping or coming off during vibration, high-speed operation, or rough terrain.

Universal 6mm Fit

With a standard 6mm outer diameter, the shaft can be used with compatible bearings, couplings, gears, and mounting components. It is suitable for both powered and unpowered wheel arrangements.

Product specifications may vary slightly between manufacturers and production batches. Product images are for illustrative purposes only and may differ from the actual product in colour, finish, dimensions, or other visual details.

Important Note

Shaft Compatibility

Confirm that your wheels, bearings, and couplings are designed for a 6mm shaft before installation.

Threaded Ends

The M3 threaded holes are intended for suitable M3 screws and washers. Select appropriate screw lengths for secure mounting without interfering with the shaft or connected components.
