Key Applications and Projects

• Heavy-Duty Robotics: Mounting large off-road rubber tires or industrial Mecanum wheels directly to the 10mm shafts of planetary gear motors.

• DIY CNC Machines & Routers: Coupling heavy lead screws or large timing belt pulleys to NEMA 34 stepper motors for precise axis control.

• Turntables and Conveyors: Attaching custom rotating platforms or conveyor belt drive rollers securely to a central drive shaft.

Unlock New Capabilities (Project Evolution) The Automated Camera Slider Pan-Tilt Head: Upgrade your automated photography rig! A standard 5mm or 8mm shaft might flex under the weight of a heavy DSLR camera and lens. By upgrading to a high-torque motor with a 10mm shaft and using this rigid 10mm flange coupler, you can bolt a solid aluminum mounting plate directly to the motor. This creates a zero-backlash, highly stable base for your pan-tilt mechanism, ensuring your time-lapse panning shots are buttery smooth and completely free of jitter!

PACKAGE INCLUDED

• 1 x 10MM Rigid Metal Flange Coupler

• 2 x M4 Set Screws (Grub Screws)

FREQUENTLY ASKED QUESTIONS (FAQ)

1. What is the exact inner bore diameter? The inner bore (d) is precisely 10mm, designed to slip smoothly over standard 10mm motor shafts.

2. What is the outer diameter of the flat flange? The flange has a total outer diameter (D) of 32mm.

3. How tall is the entire coupler assembly? The total overall height (H) of the coupler from top to bottom is 13mm.

4. How thick is the flange base? The flat flange base has a thickness (h2) of 3mm.

5. What is the diameter of the raised center section? The raised center boss has an outer diameter (d1) of 16mm.

6. What is the height of the center boss alone? The center boss height (h1) protruding above the flange is 10mm.

7. What is the distance between the mounting holes? The diagonal distance or pitch (L) between the opposite flange mounting holes is 24mm.

8. What size are the mounting holes on the flange? The four mounting holes (d2) are 4mm in diameter. This allows for standard M3 bolts to pass through easily, or M4 bolts if tapped/forced depending on tolerances.

9. How does the coupler secure to the motor shaft? It secures using two M4 set screws that thread into the side of the central boss and press tightly against the motor shaft.

10. What thread size are the set screws? The tapped holes (d3) for the set screws use an M4 thread size.

11. Are the set screws included with the purchase? Yes, two black M4 set screws are included with the metal coupler.

12. Is an Allen wrench/hex key included? No, a hex key is not included. You will need a standard metric hex key to tighten the M4 set screws.

13. What material is this coupler made from? It is manufactured from a solid, rigid silver metal alloy, typically zinc-plated steel or aluminum.

14. How many mounting holes are on the flange? There are four mounting holes evenly spaced at 90-degree intervals around the flat flange.

15. Is this a flexible coupling? No, this is a completely rigid flange coupling. It will not flex to accommodate shaft misalignment, so your components must be accurately aligned.

16. Can I use this to mount a heavy robot wheel? Absolutely. The 10mm bore variant is specifically suited for heavier robotics platforms and larger wheels.

17. Will this fit a standard NEMA 17 stepper motor? Standard NEMA 17 motors usually have a 5mm shaft. This 10mm coupler is designed for larger motors like NEMA 34 or high-torque planetary gear motors.

18. Can it mount to D-profile shafts? Yes, it works exceptionally well with D-shafts. Ensure you align one of the set screws so it presses flat against the flat portion of the D-shaft for maximum hold.

19. Can I mount a custom acrylic plate to this flange? Yes, as long as you drill the acrylic plate to match the 24mm diagonal pitch of the 4mm mounting holes.

20. Do I need to use threadlocker on the set screws? While not strictly required, using a mild threadlocker (like blue Loctite) on the set screws is highly recommended for high-vibration applications to prevent them from vibrating loose over time.
