Top notch quality

The anodized finish looks professional and seems resistant to corrosion. Assembly was quick, and the motor runs quieter than before. Will buy again for other axes.

Good value, precise fit

The aluminum alloy feels durable and lightweight. It fit my 8mm motor shaft perfectly. Took off one star because the instructions were minimal, but installation was straightforward anyway.

Great replacement part

Replaced an old rubber spider coupling with this diaphragm type. The difference in response time is significant. Just ensure you measure your shaft diameters accurately before ordering.

Reliable and robust

Been running this coupling for three months now in a dusty workshop environment. No signs of wear or loosening. The clamp mechanism holds tight.

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.

Excellent torsional stiffness

Using this for a high-speed positioning application. The double disc design handles the misalignment well without any vibration. Highly recommended for precision tasks.

5 FAQ

Q: Does this coupling come with the set screws needed for installation?

A: Yes, each coupling includes the necessary stainless steel set screws for both hubs.

Q: Is this suitable for outdoor use in rainy conditions?

A: While the aluminum is anodized for protection, we recommend using it in controlled environments. Prolonged exposure to heavy rain may affect longevity.

Q: Do I need special tools to install the clamp hubs?

A: No special tools are required. A standard hex key (Allen wrench) included in the package or a standard metric set is sufficient for tightening the clamps.

Q: What is the maximum RPM rating for the double disc version?

A: The double disc models are typically rated for speeds up to 10,000 RPM, but please check the specific datasheet for the bore size you select.

Q: Can this handle a shaft misalignment of 1 degree?

A: Absolutely. The diaphragm design is engineered to compensate for angular misalignments up to 1.5 degrees depending on the specific size model.
