## Customer Reviews

### ⭐⭐⭐⭐⭐ Z2 Precision That Glides Like Butter
*by I***Y on March 29, 2025*

AKA: The “You Didn’t Know You Needed These Until You Did” BearingsThese R188ZZs are the sleeper MVPs of anything that spins. I grabbed them for a 3D printed mini turbine project, and they’ve since found their way into a fidget spinner rebuild, a sliding drawer mod, and even a DIY rotary encoder test rig. They're shielded, compact, and smooth as silk when installed properly.Z2 tolerance means you’re getting solid mid-grade precision—not quite aerospace, but plenty good for most hobby and light industrial builds. Pop these into a printed housing or bearing block, and they’ll quietly spin forever while you admire how much smoother everything feels.

### ⭐⭐⭐⭐⭐ the desciption is correct. Or, they fit as expected
*by B***E on June 26, 2025*

nice little bearings. I needed to replace some metric with 1/4" x 1/2" o.d. and these fit nicely. I did have to shim the outside of the bearing using some .0002" brass shim stock but that was only because the the bearings were metric before and I needed to use an axle that had 1/4-20 threads on it. I have some spares too.

### ⭐⭐⭐⭐⭐ Pre greased shielded bearings
*by J***. on November 23, 2024*

Shields worked great, tried to dissolve the grease inside and couldn't.
