Great value for money

For the price, you cannot beat the quality. The bright finish makes it easy to inspect for wear. Works exactly as described for our stepper motor applications.

Excellent for encoder mounting

Used this specifically for an encoder setup. The flexibility handles minor misalignments perfectly while maintaining precision. No backlash detected so far.

Robust and reliable

We replaced several plastic couplings with these aluminum ones in our production line. The difference in durability is night and day. Highly recommended for industrial use.

Smooth operation

Installed this on a 3D printer upgrade kit. The motion is incredibly smooth now, and the noise from the motor has decreased significantly thanks to the flexible spider element.

Good quality, fast shipping

Solid aluminum construction. The spider insert provides good vibration damping. I deducted one star only because the set screws were a bit tight to start, but they loosened up fine.

Perfect fit for my CNC axis

The bright finish looks great and the machining tolerances are spot on. It connected my servo motor to the lead screw without any wobble. Very happy with the rigidity.

5 FAQ

Q: Can this handle high-speed applications above 3000 RPM?

A: Yes, the balanced aluminum alloy design is suitable for high-speed servo applications typically found in CNC and automation systems up to 4000 RPM.

Q: Does this coupling come with the rubber spider insert included?

A: Yes, the package includes the aluminum hubs and the pre-installed polyurethane spider insert ready for assembly.

Q: Do I need special tools to install the set screws?

A: No special tools are required. Standard hex keys (Allen wrenches) corresponding to the screw size provided in the kit are sufficient for installation.

Q: What are the available bore sizes for this specific model?

A: This specific listing is for the 5mm to 8mm bore configuration. Please check our other listings or contact us for custom bore sizing options.

Q: Is the bright finish coated or just polished aluminum?

A: The finish is a mechanical polish on the aluminum alloy surface. It is not anodized, which allows for better heat dissipation in some setups.
