Solved my backlash issues

After switching to this flexible coupling, the backlash in my linear actuator system was significantly reduced. Highly recommend for precision projects.

Excellent vibration damping

The soft connection feature really works. My 3D printer runs much quieter now, and there is less wear on the leadscrew bearings.

Good quality, easy install

Solid build quality and the set screws held tight under load. Installation was straightforward. Only giving 4 stars because the instructions were minimal.

Reliable for servo applications

Used this on a small robotic arm with a servo motor. It handles the angular misalignment without any binding or excessive heat generation.

Great value for money

Works exactly as described for the price point. The aluminum housing feels durable, and the spring mechanism is responsive.

Perfect for my CNC upgrade

This coupling solved the alignment issues I was having with my stepper motor. The flexible spring design absorbs vibrations perfectly, resulting in smoother cuts.

5 FAQ

Q: Does it come with the necessary set screws?

A: Yes, each package includes four high-strength set screws required to secure the coupling to both the motor shaft and the leadscrew.

Q: Can this be used outdoors in wet conditions?

A: While the aluminum is anodized for corrosion resistance, this coupling is primarily designed for indoor industrial or hobbyist environments. Prolonged exposure to moisture is not recommended.

Q: Is this compatible with NEMA 23 motors?

A: Yes, provided you select the variant with the correct bore size matching your NEMA 23 motor shaft (typically 6.35mm or 8mm). It is widely used with NEMA 17, 23, and 24 motors.

Q: What shaft diameters does this coupling support?

A: This specific LP model is available in various bore sizes ranging from 5mm to 10mm. Please check the specific variant selection at checkout for your required diameter.

Q: What is the maximum RPM rating for this coupling?

A: For optimal performance and longevity, we recommend operating this coupling at speeds up to 3000 RPM. Higher speeds may reduce the lifespan of the spring element.
