Good quality, fast shipping

The build quality is impressive for the price. It arrived quickly from large stock. I deducted one star only because the installation instructions were minimal, but it was easy enough to figure out.

Perfect fit for my CNC setup

This coupling fits perfectly between my servo motor and lead screw. The aluminum construction feels very solid, and the star-shaped insert provides great flexibility without losing torque transmission.

Reliable industrial component

We use these in several of our automated assembly lines. They handle minor misalignments well and have shown no signs of wear after months of continuous operation.

Excellent vibration damping

I replaced a rigid coupling with this spider type, and the reduction in vibration noise is noticeable immediately. My 3D printer runs much smoother now.

5 FAQ

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

A: Yes, the package includes the aluminum hubs and the pre-installed star-shaped rubber spider insert.

Q: Do you offer bulk discounts for orders over 50 units?

A: Yes, we offer tiered pricing for bulk orders. Please message us directly with your required quantity to receive a custom quote.

Q: What is the maximum torque rating for this specific model?

A: The torque rating varies by bore size. Please refer to the specific size chart in the product images or contact us with your shaft diameter for exact specifications.

Q: Is it compatible with NEMA 23 motors?

A: Compatibility depends on the shaft diameter, not just the motor frame size. If your NEMA 23 motor has a shaft diameter matching one of our available bore sizes, it will work perfectly.

Q: Can this be used in an outdoor environment?

A: While the aluminum alloy is anodized for corrosion resistance, we recommend using it in controlled indoor environments for optimal longevity, as extreme weather can affect the rubber insert.
