Good quality, fast shipping

Solid construction and good machining tolerance. It handles the high torque of my lead screw without any slipping. I deducted one star only because the instructions were minimal, but it's a standard design so easy to figure out.

Reliable industrial component

We use these in several of our automation projects. They hold up well under continuous operation and handle minor misalignments better than expected. Great value for the price point.

Perfect fit for my CNC router

This coupling replaced a worn-out part on my servo motor setup. The aluminum alloy feels very sturdy, and the elastic star element absorbs vibration perfectly. Installation was straightforward with standard set screws.

Sturdy and lightweight

The aluminum construction keeps the rotating mass low, which is great for acceleration rates on my servo system. The spider insert seems durable. Would buy again for future upgrades.

Solved my alignment issues

My motor and screw were slightly misaligned, causing premature wear on bearings. This flexible coupling compensated for the error perfectly. No more weird noises during operation!

Excellent vibration damping

I was experiencing chatter in my machine tool due to rigid coupling. Switching to this elastic spider coupling solved the issue immediately. The noise level dropped significantly, and surface finish on parts improved.

5 FAQ

Q: What is the maximum bore size available for this model?

A: This specific listing covers bores from 5mm to 20mm. Please check the selection menu for your specific shaft diameter requirements or contact us for custom sizing.

Q: Does this coupling come with the elastic spider insert included?

A: Yes, the package includes the aluminum hubs and the pre-installed elastic star spider element ready for assembly.

Q: How do I install this onto a smooth shaft without a keyway?

A: This coupling uses dual set screws per hub to lock onto smooth shafts. Ensure you tighten them securely against the flat side if you can machine one, or directly onto the round shaft using thread-locking fluid for best results.

Q: Can this be used in an environment with occasional oil exposure?

A: The aluminum alloy is anodized for resistance, and the standard nitrile rubber spider has good oil resistance. However, prolonged submersion in harsh chemicals is not recommended.

Q: Is there a warranty on the elastic element?

A: Yes, we provide a 1-year warranty against manufacturing defects for both the metal hubs and the elastic spider insert under normal operating conditions.
