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

The quantity was great for the price.. lots of DY projects

Three are a bit crunchy but the rest all spin nice after soaking in pb blaster..thx to all reviewers that suggested this. Yet to know how durable So far so good

They certainly aren’t amazing quality but they get the job done. They are pretty stiff bearings so if it’s a low torque application you might not want to use these.

These bearings arent a bad deal if you know some things going in. I am using these for a filament drybox for keeping 3D printer filament dry. Out of the box, these have a sticky machine oil/grease on them (probably to prevent rust) and do not free spin very well. If you open the seal with a knife and blast them with white lithium aerosol, they spin very easily. It doesnt look like they are packed with any kind of lubricant inside the bearings.

Great product. I recommend it to everyone.

The title says sealed Bering but the seals dot thch the inner race . dont expect them to hold up for long

Do you need a ton of 608-2RS bearings for cheap? This is that. Do you need high-quality 608 bearings with good fitting seals, fine finish and extremely tight tolerances? This is NOT that. This is 100 bearings of the mostly-right-dimensions with mostly-effective seals for the rock bottom price of 19.9 cents each. You might be able to get bearings of higher quality than these for the same $/ea, but youd have to buy 1,000+ of them. These are functional for hobby and non-critical use for a low, low price. You get what you pay for, which is to say; a butt-load of cheap bearings.

side seals are plastic and some are a bit deformed and interfere with the balls. About 1 every 15 or so are like this

I was expecting to get the same bearings in the picture which showed ABEC-7 bearings. They also came very dirty and greasy. They barely rolled and was just a half step up from the 20 year old rusty ABEC-1 bearings that were on the board before hand. Changed the wheels and trucks so I know that wasnt the problem.

Overall very decent bearings for fidget spinners. Not Amazing, but the affordability alone makes these bearings a competitive product and after thoroughly cleaning them they worked well and spin for a decent amount of time. If you are using these bearings to make spinners as gifts (as I did) then these will work just fine. If you are making them to sell… I would probably pay just a little more for a higher quality bearing. I am not sure why I liked the “single lip contact seals” of these bearing so much but they were very easy to remove for cleaning and better yet easy to put back onto the bearing afterwards. Just don’t pry them up where the “608RS” is stamped as they are thinner there and are more likely to break in that area. Taking everything into account I would say that you get a good bearing for the price. The only thing I didn’t like (which cost a star 4/5 instead of 5/5) was the lubricant that they used inside of the bearing. I am not sure if they used a silicon or what but when I received the bearings, they were stiff and sticky and didn’t want to spin. With other bearings I was used to having them packed with grease. This was not the case here. These bearings were hard to spin and were pretty much unusable directly out of the package. These bearings were not packed with grease (as many bearings are) and when I took them apart to clean them, I didn’t see any grease at all. As I mentioned before they seemed sticky as opposed to being slick or slippery and I had a difficult time even spinning them. I figured I would simply soak them in 100% Pure Acetone as this is usually enough to remove lubricants from bearings that I have worked with previously. Unfortunately, after soaking them for over 24 hours in Pure Acetone (shaking the container occasionally) they were still stiff and sticky! I almost didn’t believe it. I soaked them for another 24 hours and they were still sticky! I ended up having to use some Carburetor Cleaner and then an Engine Degreaser to cut through whatever was making them sticky. I was kind of shocked at how resilient this sticky substance was. After finally being able to remove the sticky stuff from the bearings they smelled pretty bad (engine degreaser smells). So, I soaked them in 100% Acetone again for a couple of days, took them out, sprayed them off with compressed air while spinning each one and then I let them dry. They still kind of smelled so I soaked them again in a clean container with fresh and clean Acetone and that seemed to do the trick. Kind of a lot of work I suppose. But once they were cleaned the bearings fit perfectly, spun well and helped make some pretty good custom fidget spinners. If you don’t feel like thoroughly cleaning your bearings when you receive them then you might not enjoy this particular product. If you are willing to spend some time cleaning and applying some of your own elbow GREASE to get these bearing clean and spinning properly then for the price you probably can’t go wrong.
