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

Pros: * Theyre very cheap. * They seem to be reasonably well made. Cons: * There is a lot of drag in whatever they used to lubricate these. It doesnt feel like the drag is from the bearing itself so much as it feels like they used a very heavy grease to lubricate them. I would only use these for very low-speed applications with enough torque to overcome the drag.

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.

Got these for my rollerblades and theyre just OK. Im sure there are plenty of uses for bearings that dont need to be as efficient (electric skateboard, etc.) so if you have something like that, this would be a pretty stellar deal. However, for skates and regular skateboards that you use often, you may want to look elsewhere. UPDATE: After attaching them to my skates and riding them around a little bit, they seem to have loosened up and are now gliding much more efficiently. Raising rating from 3 to 4 stars.

You get what you pay for. I realize these are only ABEC 1 rated. But, wow are they sloppy. the 8mm hole has a decent amount of variation. turned a shaft to fit the 1st bearing perfectly, the next wouldnt go on, and the next was loose.Once a shaft is fitted to the hole, ALL i tested (gave up after about 20) have more wable than Id expect. IE, spin it on a fixed shaft, and the outside casing doesnt spin even close to true with the inner casing. Some were pushing almost 1/6th inch.

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

I had purchased these to use in various 3D printer guides, but they have way too much friction. Instead of rolling they just sit there as filament passes over them. I tried printing a fidget spinner as well. As I spin the spinner as fast as I can, it comes to a complete stop within a couple of second. I guess you get what you pay for.

Like another reviewer said, you will receive a bag of mixed bearings with three different fonts on the seals. Had to sort through half the bag to find 16 that rolled smoothly. Then after installing, had to swap some out because they still didnt roll smoothly. Finish quality is poor. Worst part is I stayed optimistic that they were going to be ok and didnt determine they were junk until after the return window closed.

A quality sack of roller bearings that’s ready to roll! Each one was still properly greased, serviceable, and ready to be installed. Have yet to find any tolerance or performance defects with them, a real plus with these bargain products. 5/5, tons of Cowbell, will buy again!
