uxcell R188ZZ Deep Groove Ball Bearings Z2 1/4 Inch x 1/2 Inch x 3/16 Inch Double Shielded Chrome Steel 10pcs

If you need speed and zero friction, DO NOT BUY THESE.

These bearings are absolute garbage. They felt gritty when I got them. I put two in a tiny motor--1/40th hp--and they were very noisy and began to fail in 30 minutes. Ive never been so disappointed with an Amazon product!!!

I used these for a fishing reel. They fit just as they should have and are working great.

The inside diameter was off slightly on the small side. I got it to work but wasnt happy about the fitment

These bearings are garbage. They spin very rough and noisy.

VERY LIGHT DUTY !!! VERY VERY LIGHT DUTY BEARINGS !!!

Worked for what we needed

Just as described. Used them to make a lathe rotary tool handle

No hang-ups or snags in a 15lb low motion environment

Just the right bearing for my project
