High quality manufacturing

You can tell this was machined with precision. No burrs, perfect balance, and the diaphragm flexes smoothly. Great addition to our lab equipment.

Good value, precise fit

The coupling fits perfectly on my 10mm shaft. It handled the torque without any issues during testing. Only giving 4 stars because the set screws could be slightly higher grade.

Solid performance

Using it for a rotary encoder application. No vibration issues and the clamp style makes installation easy. Would recommend checking the bore tolerance chart before ordering.

Fast shipping and great product

Needed a replacement for a broken coupler urgently. Arrived in two days and works flawlessly. The anodized finish looks professional too.

Excellent rigidity and flexibility balance

As an automation engineer, I need components that can handle slight misalignments without sacrificing torsional stiffness. This single diaphragm design hits the sweet spot.

Perfect for my CNC upgrade

Installed this on my Z-axis servo motor. The zero backlash is noticeable immediately, and the machining quality is excellent. Very smooth operation at high speeds.

5 FAQ

Q: Does this coupling come with set screws or clamping bolts?

A: This model features a clamping style design with socket head cap screws for secure, concentric locking without damaging the shaft.

Q: What is the lead time for custom bore sizes?

A: Standard bores ship within 24 hours. Custom bore machining typically requires 3-5 business days depending on current production volume.

Q: Do you provide a torque curve chart for this specific model?

A: Yes, a detailed technical datasheet including the torque vs. angular deflection curve is available in the 'Documents' section of the product page.

Q: Is this suitable for stepper motors or only servos?

A: It is suitable for both stepper and servo motors, provided the torque and speed requirements fall within the specified limits of 15 Nm and 10,000 RPM.

Q: Can this handle a 0.05mm parallel misalignment?

A: While the coupling is flexible, we recommend staying within the specified 0.03mm parallel misalignment limit for optimal lifespan and performance. Exceeding this may reduce component life.
