600pcs 12 Size Stainless Steel Precision Steel Balls 1-8mm Metric Bicycle Bearing Balls Assortment Kit Mixing Balls 1mm 2mm 2.5mm 3mm 3.5mm 4mm 4.5mm 5mm 5.5mm 6mm 7mm 8mm K-085-600

These appear to be high quality. I have measured several of the sizes and find them right on dimension. You know how it is, you need one bearing ball and you buy 500 to get it. That said, several of the sizes have come in handy for various things (not as antifriction bearings) around the house. Not an expensive kit so it's not a high risk purchase.

These are great for what I and my wife needed them for. My wife likes the smaller balls for adding to her nail polish bottles to help thoroughly mix the polish before she applies it. They are the perfect size and weight for that. I like the larger balls for use in my acrylic paint bottles for use in my airbrushes. They get in there and really mix it up quite well, with no problems in how they function. The balls are polished steel, and when I empty a bottle, I just pour them into a paint measure cup and top it with air brush cleaner and wait about 10 minutes until all the paint is loosened up and then I rinse them with water, and put them back in the case. If you don't have airbrush cleaner, which is NOT critical for acrylic paints, you can use plain water. I recently airbrushed a 57 Chevy Belair model with 6 coats of a duplicated formula of the factory color of Matador Red, and once the bottle was empty, I cleaned the balls in water and it cleaned right up. It doesn't matter if you use acrylic or enamel paints, it does the job of getting the pigments mixed perfectly to easily flow through the airbrush. And you get enough of each size to easily do several hundred bottles. 5 stars

Just as described.

Precision is important when dealing with ball bearings, and the majority of these bearings are 100% in spec. I purchased these specifically for a project that required 5mm bearings. The project was going fantastic, except I had random jams, that I just couldn't understand. I took it apart, pulled out the bearings which visually looked fine, on closer inspection though, I found a slight flat spot on 1 of them. Yes, 1 bearing out of 50 had bit of a flat spot. It's hard to imagine this is common, but since I had 20 spares, not a big deal at all, tossed out the that bearing, replaced it with another, and a few weeks later, still working perfectly.

Good selection. Working with my setup.

The product is accurately described. I only needed one SS bearing/ball for my Michelin G735 3 1/2 ton car jack. The sizes are accurate, but they do look larger in the pics. Check the size measurements, not you impression from the pics. Mine worked out great. Good price good product.

ball bearings. they are round and make rolling friction less of an issue. assorted sizes, so you will find your application and have lots of balls laying around that you will never use. used these in a low weight bearing spinning table top. not repacking my rams rear axle.

very good quality bearings, just the sizes I needed

Muy buena calidad. Vienen enuna cajita tal como en las fotos. Recomendado.

I thought I needed ¼ inch but I’m glad I bought a set with other sizes because it turned out that I needed a smaller size.

Trae demasiada jajaja pero era justo lo que necesitaba
