Exactly as described
Dimensions are accurate. The D19L25 size fits perfectly in the tight space of my prototype. No issues so far.

Perfect for my 3D printer upgrade
Fits the 5mm shaft perfectly. Very rigid yet flexible enough to handle slight misalignment. Highly recommend for 3D printing projects.

Great value
Bought these for a CNC spindle connection. They work smoothly without vibration. Fast shipping too.

Works but instructions lacking
The coupling itself is fine, but I wish there were torque specs included for the set screws. Had to look them up online.

Good quality aluminum
The build quality is solid. I ordered the 8mm bore and it matched my encoder shaft well. One set screw was slightly tight but manageable.
Q: Can I use this for a 12mm shaft?
A: No, the maximum bore size available for this model is 10mm. Please check our larger series for 12mm shafts.
Q: Do you offer bulk discounts?
A: Yes, please contact our sales team for pricing on orders over 50 units.
Q: Does this come with set screws?
A: Yes, each coupling includes two set screws for secure mounting.
Q: Is this suitable for high-speed applications?
A: It supports up to 10,000 RPM, which is suitable for most printer and encoder applications.
Q: What is the flexibility rating?
A: This coupling compensates for angular, parallel, and axial misalignment effectively within standard tolerances.
