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

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

I bought these bearings to replace some old ones. They soon smooth and forever! Great bearings for the money!

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

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

Great, promptly delivered a good quality product. Thanks

meets the spec we needed it for. Still to early to see how durable the bearings are, but at installation they work well

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.

Clearly my inability to read and understand dimensions. these are smaller than i was designing for...but will probably use the elsewhere..

Supposed to be 10 count, 9 in package

Worked for what we needed
