Excellent torsional stiffness

As a mechanical engineer, I was looking for a coupling that could handle high torque without backlash. This aluminum alloy unit performs flawlessly. The keyway fit was precise, requiring minimal adjustment during installation.

Great value, fast shipping

The product arrived well-packaged. The three-section leaf spring design seems robust. I deducted one star only because the documentation was a bit sparse, but the part itself works exactly as expected for our automation line.

Reliable under continuous load

We have been running these couplings 24/7 in our packaging facility for six months now. No signs of wear or fatigue. The elastic connection sleeve effectively absorbs minor misalignments, protecting our expensive servo motors.

Perfect for our CNC retrofit

We installed these triple diaphragm couplings on our older CNC machines during a servo upgrade. The alignment tolerance was forgiving, and the vibration damping is noticeable. Build quality feels very solid, matching the description of Japanese precision standards.

Superior to previous brand

Switched from a different manufacturer to this Tsugami-style coupling. The difference in smoothness during acceleration and deceleration phases is immediate. Highly recommend for anyone needing high-precision motion control.

Solid construction

Very happy with the aluminum alloy quality. It is lightweight yet strong. Installation was straightforward with the provided keyway. Would purchase again for future projects.

5 FAQ

Q: Does this coupling come in different bore sizes?

A: Yes, we offer various bore sizes to match standard servo motor shafts. Please select your specific size from the dropdown menu or contact us for custom machining options.

Q: Can this be used for stepper motors or only servos?

A: While optimized for servo motors with keyways, this coupling is also fully compatible with stepper motors and other precision drive systems requiring zero-backlash connections.

Q: Do you provide installation torque specifications?

A: Yes, detailed installation instructions including specific torque values for the clamp screws are included in the product package and are also available for download on our support page.

Q: What is the maximum allowable parallel misalignment?

A: For the triple diaphragm model, the maximum allowable parallel misalignment is typically 0.2mm, though this can vary slightly by specific bore size. Please refer to the technical datasheet included with your order.

Q: Is the 4-year warranty valid for industrial continuous use?

A: Absolutely. The 4-year warranty covers defects in materials and workmanship even under continuous industrial operation, provided the unit is installed within the specified torque and misalignment limits.
