100 Pack 608-2RS Skateboard Bearing, Rolling Bearings, 8x22x7mm 608rs Bearing

I ordered these because I have some applications that go through bearings quickly and quality wasnt my main concern. I was very impressed with the bearings I received. They came in ten tubes of ten bearings in two seperate boxes. With this quantity of bearings for this price I expected a decent number of defects, but Id estimate issues with less than 10% of the bearings. Thats an acceptable rate to me for the price.

I am making a project that needs 12 bearings. I got 100 for the same price of the twelve. At that price I just have to think up more projects.

Great value for the price.

Multiple already rusty within packaging.

Yup, they are bearings. But would not give above a C rating for condition, even at this price. Packing was lacking. All just in a big bag. I found at least 3 different labels on the seals so thinking its a mixed batch of brands. Probably why some seem ok and some not so much. Also cleanliness control was lacking somewhere. as several of them have heavy grit all over. Normally would not care that much, but considering the seal is questionable on many of them as well, its likely the grit got into some. Wanted to use out of the bag, not have to clean and re-lube before use. One seal was missing a part altogether, and others have gap where you can see the bearing inside. Would have been just as well to get non-sealed bearings.

As advertised

I thought hardening at the very least a requirement for roller bearings. I guess thats what I get for ordering chinese crap. Save your money.

Made a sliding drawer bearings working for sliding drawer excellently

This is a really great bearing

No nylon cage contrary to description. Metal cage. Non removable type.. Seals (shields?) are black, not red (not that it matters that much) but made of thin, flimsy plastic material. All the bearing shields Ive seen have been made of some type of thin metal alloy material, with a rubberized coating on one side. Not these. These flex a lot and dont seem too precise a fit, compared to the other type. The bearings had kind of a scraping quality to them, not smooth or particularly quiet. I had heard that its better to buy cheap bearings because the ABEC rating doesnt matter all that much unless its a very, very high RPM application youre using them for and that if you go for a higher ABEC rating, youre just wasting your money.. But I suspect theres something going on with these bearings that doesnt have to do with the ABEC rating at all. Not sure what it is. But maybe the moral of the story is that you just cant get 100 good quality bearings for $20? Perhaps. * Since originally posting this, Ive come to the conclusion that the problem lies with the metal cages that hold the individual ball bearings in these bearings. Because everything else about them, with the exception of the flimsy black plastic shields that probably arent really contributing to any problems (despite being flimsy) ...everything else about these bearings seems to be fairly similar in quality to other similar bearings that Ive had EXCEPT for these metal cages. They just seem to be made of a very thin metal and also seem quite flimsy and not precise.. and they are important. In fact I noticed that one of the individual ball bearings in one of these cages wasnt even centered properly in its little cup. So I think this is the problem. Which is why they scrape and do not roll smoothly in my opinion
