Violet R. ★★★★★

Installed this under my X3 mill's bearing and the fit was precise with no wobble. The 3 mm height matched the original perfectly and the metal feels solid.

Robert E. ★★★★★

The 3 mm thickness was spot-on for my X3 mill spindle below the bearing, and the fit was snug without any wobble. It took just minutes to swap in and get everything aligned properly again.

Isabella U. ★★★★★

I needed a precise 3 mm spacer to keep the bearing seated correctly on my X3 mill's spindle, and this one dropped right into place with no play or wobble. The fit is exactly what I was hoping for.
