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

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.

So the price is good and they are bearings. Not very smooth, so like not for fidget spinners and the like. I’m sure they work for certain applications

Excellent delivery, great craftsmanship, performed exactly as needed!

Im sure these will work to support light to medium weight loads and you cant beat the price.

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

85/100 worked. 15 either broken or wont rotate. If this was a hug school exam Id say hey, solid B! But it isnt, so I gave it 3 stars instead of 4. If you need 100 working bearings youll want to order more than one package. If you only needed half, like I did, this works out ok.

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.

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.

Really good bearings for the price. Quality seems good and very smooth.

These are excellent 608 bearings for NON-SKATE use such as bearings for 3D printer parts. You can get rid of grease within seconds by simply dipping in some lighter fluid. They work fine after or you can add a little bearing oil. Also the sleeves are junk, just use without. These bearings would be good for applications that dont deal with dirt such as actual skateboarding. They are perfect for other uses.
