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

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.

They come in cosmaline i do believe to keep off rust. Out of 20 I found 2 didnt spin right. I clean em woth gasoline and wash n dry with dawn and relube.I notice on my skates I can run a set for about 6 months before relubing.

Good bearings. Slight surface corrosion on outside but none visible under seals. Light coat of oil here and there but no evidence of intentional lubrication inside. Clean, lubricate, and inspect seals before use.

These bearings are not hardened as advertised. Upon disassembling, the bearing races and even bearing balls were not hardened and could be easily deformed with slight pressure between pliers and were also easily filed with low grade carbon steel hand files. The wobble was also significant, with the inner shaft and outer being able to skew in excess of 4 degrees without load. The seals were also garbage with holes and flashing still present, but that of lesser importance. Perhaps a more telling sign is the warning in the photo: Note... not professional bearings. That is, these are not bearings any company would use in a consumer product. Because they are not precise, wear will increase. Because they are not hardened, they will easily abrade away. The thick grease is likely there to disguise the rough texture of the races and the already malformed balls. If you use these bearings, do not do so in an expensive piece of equipment or in a skateboard where a bearing failure could mean a trip to the hospital. Go ahead and drop the same amount of money on 6-12 good bearings from a reputable source. If, however, you are going to make a fidget spinner, go nuts. Thats about the only use where quality is of second concern.

These are not suitable for skating, or fidget spinners. They are full of heavy grease, and the plastic cover rubs on the inner bearings balls. The bearings are probably made for very heavy machine loads, because the ball cage is metal and double sides. Even de-greasing them and re-applying a light lubricant will not work. Maybe for other uses this bearing is OK, but definitely not OK as a skateboard bearing, which is what the product has in the title during the time of purchase and review.

Made a sliding drawer bearings working for sliding drawer excellently

OK, just OK. You get your moneys worth, but dont expect too much when you are paying about 25 cents per bearing. They arrive in industrial dirty condition, so you need to wipe them down with some WD-40 before use. Check them individually, I had one bearing missing a seal, and one bearing that was just useless. Several are grindy enough that I will use them only if necessary. The seals are good if you will be using these bearings in a dirty environment, such as shaping wood with a CNC. But the seals alo add friction, since they tend to rub against the inside of the bearings. If you are using just a few bearings, I would get better quality over quantity.

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.

So I opened the a contaner, each one has a set of ten. First thing I noticed is the seals looked odd. So I pop one out, they are plastic, not rubber of any kind. Thereis very very little grease inside, could be a good thing or bad depending on your use. My intened use is for a bearing to last so I need grease inside. So I check 10 more same thing. That takes me to the biggest problem. These called seals you can see the balls inside with the seals in place from the factory. No way will they seal in the grease or keep dirt out.
