Joshua Y. ★★★★★

The fit is snug and precise over the bearing, exactly what I needed for the X3 mill. It took maybe two minutes to install and everything lines up perfectly now.

Scarlett G. ★★★★★

Was a bit skeptical about aftermarket spacers, but this one sits flush on the bearing and the alignment on my X3 mill feels spot-on now, no more wobble during cuts.

Brian ★★★★★

Put this on the X3 spindle and the 3.5 mm bore keeps everything aligned perfectly so bearings sit where they should. Nice cheap fix compared to hunting for a custom part.
