Perfect for my CNC upgrade

This coupling fits perfectly on my NEMA 23 stepper motor. The aluminum build quality is excellent, and the spider insert provides just the right amount of flexibility to handle minor misalignments without losing torque.

Exceeded expectations

I was worried about backlash, but this coupling maintains precision while allowing for angular misalignment. Highly recommend for anyone building a custom motion control system.

Reliable high torque performance

Running this at high loads for weeks now with no signs of wear. The ACCD brand seems very reliable. The black anodized finish also looks professional in the assembly.

Good value for money

Does exactly what it is supposed to do. The bore sizes were accurate, and the set screws hold tight. A solid choice for industrial automation projects.

Solid construction

Very sturdy coupling. Installation was straightforward with the clamp screws. I deducted one star only because the instructions were minimal, but the product itself works great for my servo reduction setup.

Great vibration damping

I replaced a rigid coupling with this three-jaw star type, and the noise level in my machine dropped significantly. The elastic element really does absorb vibrations effectively.

5 FAQ

Q: Does this come with the mounting screws?

A: Yes, each coupling unit comes complete with the necessary high-strength clamp screws and an Allen key for immediate installation.

Q: Can this coupling handle angular misalignment?

A: Yes, the three-jaw star-type design with the elastic spider insert is specifically engineered to compensate for angular, parallel, and axial misalignments.

Q: Is the spider insert replaceable if it wears out?

A: Absolutely. The elastic polyurethane spider is designed to be easily replaced without removing the hubs from the motor or drive shafts, minimizing downtime.

Q: What are the available bore sizes for this coupling?

A: We offer a wide range of bore sizes to fit various stepper and servo motor shafts. Please check the specific variant selection menu or contact us for custom boring options.

Q: What is the maximum operating temperature?

A: The standard polyurethane spider element typically operates efficiently between -30°C and +80°C. For extreme temperature environments, please inquire about specialized elastomer options.
