Perfect fit for my CNC router

The build quality is exceptional. The aluminum hubs are precisely machined, and the elastic pad fits snugly without any play. It eliminated the vibration issues I was having with my previous rigid coupling.

Reliable industrial component

I have installed these on three different automation projects. They handle minor misalignments perfectly and the elastic spider provides excellent damping. Highly recommended for precision applications.

Exceeded expectations

Direct sales meant a great price, but I wasn't sure about the quality. I was pleasantly surprised. The tolerances are tight, and the elastic pad is high quality rubber that shouldn't degrade quickly.

Smooth operation and easy install

Installation took less than 10 minutes. The jaw design allows for easy assembly even in tight spaces. My machine runs much smoother now with significantly reduced noise levels.

Great value for direct sales

Works exactly as described for connecting my servo motor. The clamping mechanism is strong and holds the shaft securely. Only giving 4 stars because the included Allen key felt a bit soft, but the coupling itself is top-notch.

Solid construction

The anodized finish looks professional and seems durable. It handles the torque of my 400W servo motor without any slipping. A very reliable purchase for the price point.

5 FAQ

Q: Can this coupling be used in a high-temperature environment like near an oven?

A: The standard NBR elastic pad is rated up to 80°C. For environments exceeding this temperature, we recommend contacting us for a version with a Viton or Hytrel spider which offers higher heat resistance.

Q: What is the lead time for bulk orders of 50 units?

A: For bulk orders of 50 units or more, our typical lead time is 3-5 business days for processing before shipment. Please contact our sales team directly for volume discount pricing.

Q: Does this come with a keyway or is it keyless?

A: This is a keyless coupling that utilizes a clamping screw mechanism. This allows for zero-backlash transmission and easier installation compared to traditional keyed couplings.

Q: What is the maximum bore size this coupling can accommodate?

A: This specific model supports bore sizes ranging from 5mm to 20mm. Please check the detailed specification table in the product images to select the correct size for your shaft.

Q: Is the elastic spider replaceable if it wears out?

A: Yes, the elastic spider (jaw pad) is designed to be easily replaceable. You do not need to remove the hubs from the shafts to swap out the worn elastic element.
