uxcell 623ZZ Ball Bearing 3mm x 10mm x 4mm Double Shielded 623-2Z 80023 Deep Groove Bearings, Carbon Steel (Pack of 20)

The bearings are well made and at great price. I was needing a bearing to replace one that was worn out in a yard ornament. The new bearing fit my application great and was a good value.

These bearings seem fine to replace those in a local museum's Van de Graff generator's globe static collector.They are much cheaper that McMaster Carr and appear to have precise dimensions and very little runout. We will see how long they last...

Works great

It was just what I wanted.

Not the best QC, as some of them don't have a smooth rotation and are a little grindy/sticky.but for the most part they work.

Used to remove friction heat from powder actuated machine that had pins in holes now holes are bearings

Used them to replace bearings in yard wind rotating things. They w0rk great.

Exactly what I ordered on time delivery

Me encantó la suavidad de estos rodamientos

As the title says

The product is ok for the bargain.pro:-the size is accurate.-good for simple projects.-competitive price.cons:-TOOK 2.5 WEEKS!! to ship to Canada.-not smooth bearings as you would expect.-doesn't feel as durable as the quality goes, comparing to other products I purchased through amazon.-the middle circle (frame) is not aligned correctly. (see the image)I did not try them yet, but these are my first impressions about the product so far.

Good

Very sloppy fit. ID and OD out by .03 to .04mm
