Perfect for CNC Retrofit

Installed this on my milling machine servo setup. The keyway fit was precise and there is no backlash. Very satisfied with the build quality.

Excellent Vibration Damping

The elastic star element does a great job reducing noise and vibration. My motor runs much smoother now.

Good Value for Money

Works well for my lathe project. The aluminum feels sturdy. Shipping took a bit longer than expected but the product is solid.

Solid Build Quality

Heavy duty feel and works as described. Would prefer if it came with a spare spider insert, but overall a good purchase.
