uxcell 7mm Bearing Balls 304 Stainless Steel G100 Precision Balls 20pcs

From what I can tell, the quality is very good. I ended up using one of the balls in my pressure washer where the original ball had a chip in it, which would cause my pressure washer to leak when I let go of the handle sounds silly, but it worked great

Haven't used them but they are as advertised

I have an old worm and ball steering gear box from a chevy S10 that we have cut open and use for demonstration, adjustments etc.

Exact size for a wood animated puzzle that uses ball bearing this size . The one you turn the hand crank and the balls go down different paths. I had lost a couple and measured diameter and they were 11 mm and these where exact size . Verified with calipers.

Great

I got these for a marble machine for my dad, I'm super glad they were the right size. The price 9s fair so if any get lost it's easy to replace.

The media could not be loaded. I bought these steel balls to replace the ones I lost with the Marble Run I was building. They were exactly the size I needed

I only realized (after I opened the product) that these stainless steel ball bearings don't respond to a magnetic field (which is why I bought them to begin with). I didn't know that they actually made stainless steel ball that don't respond to magnets. Does anyone know why these don't respond to magnets, and what should I look for when searching for stainless steel balls (other than the size) that DO respond to a magnetic field? The error on ordering these was mine, and they didn't cost much, so I'll keep them, but I'm concerned about ordering any others until I know what to look for.
