Solved my alignment problems

I had minor misalignment between my motor and ball screw. This flexible coupling compensated perfectly and eliminated the noise.

Perfect fit for my CNC upgrade

This coupling solved the vibration issues I was having with my stepper motor. The aluminum build feels solid and the keyway ensures no slippage under load.

Great value for money

Solid engineering at a reasonable price. It's not the fanciest coupling out there, but it gets the job done reliably for industrial use.

Excellent damping capabilities

The spider insert does a fantastic job of absorbing shocks. My servo motor runs much smoother now. Highly recommended for precision applications.

Good quality, slightly tight fit

The construction is excellent and it handles high torque well. Had to file the bore slightly to get it onto my specific shaft diameter, but otherwise great.

Robust and reliable

Been running this on my lathe for three months without any issues. The variable diameter design made it easy to adapt to my existing setup.

5 FAQ

Q: What is the maximum operating temperature for the elastomer insert?

A: The standard elastomer insert is rated for continuous operation up to 80°C (176°F). For higher temperatures, please contact us for alternative materials.

Q: Does this come with the bolts and set screws needed for installation?

A: Yes, the package includes all necessary mounting bolts and set screws required for immediate installation.

Q: How do I replace the spider insert if it wears out?

A: The coupling is designed for easy maintenance. Simply remove the bolts separating the two hubs, slide out the old insert, and replace it with a new one without removing the hubs from the shafts.

Q: Can this handle angular misalignment?

A: Absolutely. The spider design allows for significant angular, parallel, and axial misalignment compensation while transmitting torque efficiently.

Q: Is the keyway standard sized or custom?

A: The keyway adheres to standard ISO metric dimensions corresponding to the selected shaft diameter range.
