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

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.

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

This was a very good product very good shipping timely would definitely do business with again

WayneChicago wrote an excellent review. You should read that before reading mine. He outlines is perfect detail all the reasons why people buying these are complaining. Only he says it with tact and finesse. But I dont have that. So if you want a more direct rebuttal to the absolute nonsense youll read in the product review section about these being akin to sand-filled garbage, then keep reading. However, If sciency words are just flowery nerdspeak to you and breaks your brain, then just sop reading now and go buy the grossly overpriced BONES bearings. They make the cool whizzing sound on first rip out of the box. Plus theyre all shiny and you cant put a price on shiny, can you? Now....If youre not a mental tree stump and words with more than 3 syllables dont frighten you, then by all means, continue on! General Complaint: These are covered in some kind of oil and dont spin. Rebuttal: That is CORRECT! The insides are packed with grease which is thick. Think cooled bacon grease. When you reheat cooled bacon grease, what happens to it? It thins out and becomes more viscous, right?? Same thing applies here. These are packed with grease because theyre designed to be run in machines for long periods of time. Which means heat from rotational friction, which means the grease viscosity inside the bearing thins due to thermal conduction. This is WHY they were built the way they come in the box. So you can use them in machine type applications right out of the box, where thermal friction needs to be considered. Ok, but can I still use them for skateboard or roller skate wheels though? YES, you can but you need to do a little work first. No big deal if youre not lazy. If you want these bearings to spin like a fidget spinner and go whizzzzzzz, you have to dissolve the grease inside the bearings and use a thinner lubricating agent in its place. WayneChicago goes over how to do just that in his review. So I dont have to. Thanks, Wayne! *fistbump* And if you cant find WayneChicagos review, dont act like you dont have Google. Just look up How to dissolve grease in ball bearings. This isnt rocket science... As far as I can tell, the outside grease feel is just machining oil which is often times applied to metal surfaces as a water repellant to keep the surfaces from rusting due to atmospheric conditions. Wood workers and machine shop operators know exactly what Im talking about. Probably some mechanics too. Why would they do that? Well...where are these things made? Is there any water that might get into the bearings in transit from the factory to your house? Yeah, there is. Theres literally an ocean of it. Highly corrosive salt water to boot. So, in order to make sure these dont arrive as little jammed up rust cakes at your doorstep courtesy of the Amazon delivery guy, they coat them in a light oil or maybe even some of the inner grease to prevent that from happening. Youre WELCOME!! Its a prophylactic measure against people who dont know better. And also so people dont buy these and end up in their review section complaining about that too. Like so many other people are out here doing. The people complaining simply dont know what they dont know. And are trashing a decent product for the price from a company that is CLEARLY putting in an honest effort to deliver value to the consumer for a VERY REASONABLE PRICE. Some of these might have manufacturing defects, Some might last longer than others. When I bought mine they were under $0.30 each. Im not putting mine under heavy load for long durations anyways, and Ill have PLENTY of replacements should some of them give out, as they sometimes do. I have not tested them yet but I dont need to to know that I DID NOT get screwed on the transaction. This is EXACTLY what I expected and Im sure will exceed my expectations in performance. Sure, you get what you pay for. But if you know what you need to know before making a purchase, youll find INCREDIBLE value in these bearings given youre buying them for the right application. If you find yourself with a chapped ass complaining about this product because you didnt know what you needed to know before making the purchase, chances are you also didnt take my advice and spring for the BONES. And thats on you, playa... -5 Stars.

Used product for various projects, and liked that there were lots of them for cheap.

Did not fit as expected, fits sloppily on the axle what about a half a millimeter of Clarence although this may have been partially my fault but

I used these bearings on two pairs of rollerblades. 32 bearings. 1/2 are breaking down and have spilled grease. 1 bearing completely blew out and shot bearings everywhere. Ive been rollerblading since 93. Its the bearings. Unsafe at any speed.

We used them in roller skates. They are extremely rough bearings. And in a week or 2 some keep locking up very unhappy with them

As advertised

Got a lot that were missing 1 bearing and some that didnt even have the clips closed. If you buy these, make sure you remove all the sides and check them before use. You will need to soak them in gas to degrease them and then use whatever lubricant you prefer.
