Solid performance

Works as described. The TPU material holds up well under continuous rotation. Only wish they came in a bulk pack option.

Excellent vibration damping

The flexible sleeve significantly reduces noise and vibration transmission between the motor and the encoder. Very satisfied with the quality.

Perfect fit for our encoders

These TPU couplings are exactly what we needed for our motor encoder setups. The figure-8 design absorbs vibration well and the installation was tool-free.

Durable and reliable

We have been using these in an industrial environment for three months with no signs of wear. The oil resistance is a huge plus for our machinery.

Great for DIY projects

Easy to snap onto the shafts without needing set screws. Saved me a lot of time on my CNC router build. Highly recommended for hobbyists.

Good flexibility, slight odor initially

The elasticity is great for compensating minor shaft misalignments. There was a slight rubber smell out of the box, but it dissipated after a day of operation.

5 FAQ

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

A: Yes, the lightweight TPU construction makes it suitable for high-speed encoder applications, provided the torque requirements remain within low to medium ranges.

Q: How do I remove the coupling if I need to replace it?

A: Simply grip the ends of the figure-8 sleeve and pull gently while twisting slightly to slide it off the shafts. No tools are required for removal.

Q: What is the maximum angular misalignment this coupling can handle?

A: This Figure-8 coupling can typically compensate for angular misalignments up to 5 degrees, depending on the specific shaft diameters used.

Q: Can I use this in an outdoor environment?

A: While the TPU material is weather-resistant, we recommend housing the coupling in a protective enclosure if it will be exposed to direct UV sunlight or extreme weather conditions for prolonged periods.

Q: Does this come in different sizes for various shaft diameters?

A: Yes, we offer this Figure-8 coupling in multiple bore sizes to fit standard encoder and motor shafts. Please check the size selection menu for availability.
