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

These worked great on my Zebco 33 Max, gave it much smoother action on it by replacing the bearings in it with these.

None of the bearings shipped was smooth. So much resistance when tried to spin them.

Great! Just what I wanted. Works as advertised.

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

I do a lot of template routing. I have a Whiteside hinge mortise bit that I mostly use for relief-sculpture-style stock removal. The carbide is excellent, but the process eats bearings. These are great, affordable replacements.

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!!!

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

super loose tolerances, below average for machine work

These are good bearings but the side casing comes off easy, I had to remove them after putting them on and the side casing fell right off I was able to snap it back on and I’m still using them they were great

Low quality bearings, rotation is not smooth without load, do not work for low load applications where low friction is important
