Exceeded expectations

Bought this for a servo motor application. The flexibility of the spider element absorbs shocks perfectly. Delivery was fast, and the packaging protected the item well.

Good value for the price

Works well for my 3D printer upgrade. The spider element provides good damping. I deducted one star only because the set screws could be slightly higher grade, but overall a solid purchase.

Robust and reliable

I use these in an industrial automation project. They handle high torque loads without slipping or deforming. The zero backlash claim seems accurate based on our precision tests.

Perfect fit for my CNC router

This coupling replaced a worn-out part on my spindle motor. The build quality is excellent, and the aluminum hubs feel very sturdy. Installation was straightforward, and there is absolutely no vibration now.

Easy to install

Very happy with this product. The bore sizes were exact, and the clamping mechanism holds tight. It solved my alignment issues immediately.

Solid construction

The anodized finish looks professional and resists corrosion. It runs quietly even at high RPMs. A great replacement for OEM parts that cost three times as much.

5 FAQ

Q: Do you offer different hardness levels for the spider?

A: Standard units come with a medium-hardness polyurethane spider. Custom orders for different hardness levels may be available upon request.

Q: Can I replace just the spider element if it wears out?

A: Absolutely. The spider element is designed to be replaceable without removing the hubs from the shafts, saving you time and money on maintenance.

Q: Is this suitable for outdoor applications?

A: Yes, the black anodized aluminum hubs offer good corrosion resistance. However, for harsh chemical environments, we recommend additional protective measures.

Q: What is the maximum RPM rating for this model?

A: Depending on the specific bore size, these couplings are generally rated for up to 4000 RPM. Please check the detailed specification sheet for your specific size.

Q: Does this coupling come with set screws included?

A: Yes, each hub comes pre-installed with high-tensile set screws ready for immediate use.
