Good value, slight runout

Works great for low-speed applications. I noticed a tiny bit of runout at max speed, but it's within acceptable limits for my encoder setup.

Great for CNC retrofits

Used these to replace old rigid couplers on my milling machine. The noise reduction is immediate, and motor life should improve.

Perfect fit for my servo project

The figure-8 design absorbs vibration really well. Installation was straightforward, and the machining quality is excellent for the price point.

Excellent build quality

The aluminum hubs are anodized nicely, and the elastomer element feels durable. No issues after two weeks of continuous operation.

Robust and flexible

I needed something to handle angular misalignment, and this GB type coupling handles it perfectly without binding. Highly recommended.

Decent but sizing was tricky

The product itself is fine, but make sure you measure your shaft diameters twice. The tolerance is standard, but I had to ream one side slightly.
