500Pcs Assorted Loose Bicycle Bearing Balls 1/8, 5/32, 3/16 7/32 and 1/4

Do not buy these bearings! I wanted to rebuild a rear bicycle hub (Shimano Deore) and the bearings I got were entirely useless for any mechanical application. I threw them all out when I saw the severe pitting and deep gouging throughout more than 20 1/4 balls.

The finish is good

I knew I needed some ball bearings but didn’t know the exact size. Well it’s one of these. Now I have plenty for next times.

My sample of the 1/4 balls indicated a typical size of 0.2498 with a standard deviation of 35 millionths of an inch. These fixed my bicycle tires rough rotation, so for the price I am happy. Good set to have handy.

These are dead nuts on for size too the tenth but not hard steel. Easily dented with a hammer. Ok for projects and measurements but not going to carry fatigue load like a real hardened ball bearing.

Works great

This was a great kit for some home diy projects that needed them. Its enough variety to make sure that you dont have to keep going back to the store to get a different size. I used them for my Bike hub when it was getting loose. The quality looks good but I have no means of testing that. Over all a solid deal on the market.

Unfortunately sizing was off

They come individually packaged by size. They seem hard and they don’t rust. Work as they should.

As advertised. I miked some bearings , all within 10-15 ten thousandths. Good enough for a bicycle.
