Reduced Noise Significantly

Replaced an old rigid coupling with this. The elastic spider absorbs shocks really well.

Excellent for CNC Projects

This coupling fits perfectly on my lead screw setup. Vibration is minimal and the build quality is solid.

Good Value for Money

Works well for my servo motor. Slightly tight fit on the shaft but manageable with care.
