Great value for money

For the price, you cannot beat this coupling. It handles minor misalignments very well. I wish it came in more colors, but functionally it is spot on.

Durable and reliable

Been running this setup continuously for three weeks now. No signs of wear or tearing. The elastic properties hold up well under constant rotation.

Excellent vibration dampening

I used this to connect a small encoder to a stepper motor. The TPU material does an amazing job of dampening vibrations, resulting in smoother readings. Very satisfied with the purchase.

Easy to install

Installation was a breeze. Just push it onto the shafts and you are done. No tools required. It grips tightly and hasn't slipped once during testing.

Perfect fit for my encoder project

This figure-8 coupling fits perfectly on my motor shaft. The polyurethane material provides just the right amount of flexibility without losing torque transmission. Highly recommended for precision tasks.

Good quality, slightly stiff at first

The build quality is excellent. It was a bit stiff when I first installed it, but after a few hours of operation, it loosened up nicely. Works great for reducing vibration.

5 FAQ

Q: Does this come in different hardness levels?

A: Currently, we stock the standard hardness grade which offers the best balance between flexibility and torque transmission for most encoder applications.

Q: Can this be used in outdoor environments?

A: While the TPU material is resistant to moisture and UV light to some extent, we recommend housing it within an enclosure for prolonged outdoor use to ensure maximum lifespan.

Q: How do I remove the coupling if I need to change the shaft?

A: You can gently twist and pull the coupling off the shaft. If it is tight, using a slight amount of isopropyl alcohol on the shaft interface can help loosen the grip without damaging the part.

Q: What is the maximum shaft diameter this coupling supports?

A: This specific model is designed for standard encoder shafts ranging from 4mm to 6mm. Please check the product variation list for exact sizing options.

Q: Is this coupling suitable for high-speed applications?

A: Yes, the polyurethane material is balanced for high-speed rotation, typically up to 3000 RPM, depending on the specific load and alignment.
