Robust and reliable

Used these for a custom automation project. The stainless steel screws are high quality and haven't stripped during installation. Very satisfied with the durability.

Exceeded expectations

For the price, you cannot beat the precision of this coupling. It runs smoothly at high RPMs without generating excessive heat or vibration.

Good stiffness

The bellows provide excellent torsional stiffness while still accommodating slight misalignments. Installation was straightforward with the provided hex key.

Great value, minor finish issue

Functionally, this coupling works perfectly on my 3D printer Z-axis. There was a tiny scratch on the aluminum housing, but it doesn't affect performance at all.

Zero backlash observed

I replaced my old rubber spider coupling with this bellows type, and the difference in print quality is noticeable. No more layer shifting due to coupling flex.

Perfect fit for my CNC router

The build quality is exceptional. The clamping mechanism holds the shafts securely without any slip, even under high torque loads. Highly recommended for precision applications.

5 FAQ

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

A: This model features a dual-clamping screw design for both hubs, eliminating the need for traditional set screws and preventing shaft damage.

Q: Is the bellows material resistant to coolant fluids?

A: Yes, the stainless steel bellows are highly resistant to common industrial coolants and oils, making them suitable for machine tool environments.

Q: Can I use this with a 8mm motor shaft and a 10mm lead screw?

A: Absolutely. We offer various bore combinations. Please select the '8mm x 10mm' option from the dropdown menu when placing your order.

Q: What is the maximum allowable parallel misalignment for this size?

A: For the standard sizes in this series, the maximum allowable parallel misalignment is typically 0.2mm, though please check the specific datasheet for your chosen bore size.

Q: Do you provide a torque specification sheet for installation?

A: Yes, a detailed installation guide including recommended tightening torques for the clamping screws is included in the package and available on our product page.
