Mount wheels, discs, and mechanisms securely to your motor shaft with this Flange Shaft Mounting Hub, a compact aluminum alloy coupling designed to bridge a round motor shaft to a flat, bolt-on component. Rather than joining two shafts together, this hub gives your shaft a flanged mounting face with bolt holes, making it easy to attach wheels, gears, discs, or custom 3D-printed and laser-cut parts directly onto a motor’s output shaft.

The hub clamps onto the shaft using set screws through the side of the cylindrical body, while the circular flange face includes multiple through-holes for bolting on whatever component you’re mounting. This design keeps the connection rigid and well-aligned, reducing wobble and runout compared to friction-fit or adhesive mounting methods. The aluminum alloy construction is lightweight yet durable, resisting corrosion and holding up well to repeated assembly and disassembly.

This mounting hub is a common component in robotics and RC builds, used to attach wheels to DC gear motors, mount discs to rotary mechanisms, or connect custom parts to a motor shaft in DIY automation projects. It’s typically supplied with the mounting hex key and set screws needed for installation, making it a ready-to-use solution for hobbyists building robot chassis, Mecanum wheel platforms, and other shaft-driven mechanisms.
