Solid component

Does exactly what it says. The anodized finish looks professional and seems resistant to shop oils. Fits standard shaft sizes perfectly. Would buy again if I need more for other axes.

Solved my vibration problem

My previous rigid coupling was causing too much stress on the motor bearings. Switching to this flexible star coupling eliminated the vibration immediately. The machining precision on the aluminum body is top-notch.

Robust and reliable

I have been running this coupling at high RPMs for three weeks now with no signs of wear. The flexible star insert does a great job dampening minor misalignments. Highly recommended for hobbyist CNC builds.

Great for high torque applications

Using this on a heavy-duty Z-axis setup. It handles the load without slipping or deforming. The clamp mechanism holds very tight. Excellent product for the price point.

Perfect fit for my CNC router

This coupling replaced a worn-out part on my stepper motor setup. The aluminum build feels solid, and the zero backlash is noticeable in the finish quality of my cuts. Installation was straightforward with the clamp screws.

Good value, works as expected

Bought this for a servo lead screw application. It handles the torque well without any vibration issues. The only reason for 4 stars is that the instruction diagram was a bit small, but the product itself is excellent.

5 FAQ

Q: Does this coupling come with the elastomer star insert included?

A: Yes, the package includes the aluminum hubs and the pre-installed flexible elastomer star insert ready for use.

Q: Is the material suitable for environments with occasional coolant exposure?

A: The aluminum alloy is black anodized which provides good corrosion resistance. However, prolonged submersion in aggressive coolants is not recommended; wiping it down after exposure is advised.

Q: Can I use this with a 10mm motor shaft and a 12mm lead screw?

A: Yes, we offer various bore combinations. Please select the specific SKU that matches your 10mm to 12mm requirement from the options dropdown before ordering.

Q: How do I properly torque the clamp screws?

A: Please refer to the technical datasheet provided in the product images for specific torque values based on your shaft diameter. Generally, tighten evenly in a cross pattern to ensure concentric clamping.

Q: What is the maximum allowable angular misalignment for this model?

A: This star coupling can typically accommodate an angular misalignment of up to 1.5 degrees, depending on the specific bore size and operational speed.
