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

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

Great price but they were not big enough

Broke the front axle in my Alex 29er wheel so I got a new axel and these to replace the OE bearing. These bearings are high quality for the price. These should be on the shelf of anyone who rides bikes.

For the most part these bearings are great, but there are a few bearings that have tiny indents in them. Good quality otherwise. As expected for the price.

calipers say theyre accurate and theyre separated and labeled, what more can you ask for?

Visual inspection - I didnt count them. Five sizes in zipped bags, lightly lubricated. All enclosed in a sealed clear plastic bag. The product looks good, no extraneous material. Labeled Qingzheng and made in China.

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.

Buying this quantity, of this particular item made me uncomfortable. I really only needed a few. That said, they make great acrylic paint and pigment agitators.

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.
