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.

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.

These are nowhere near quality bearings, but they are great for makers who use bearings in their projects and need the quantity without breaking the bank.

I rarely leave negative reviews, but this was an incredibly poor quality product. I should have realized that a 100 pack of skateboard bearings would not deliver the best quality or consistency, but I bought this without better judgement. I sheared my first 2 bearings in the first week. I shredded a couple more before I finally vowed to not use these again. I suppose these cheap quality bearings could be used in a pinch, but they are slower (more friction) than good bearings, and will break WAYYY quicker than any quality materials. You will get good at riding without functional bearings if you try to use these very long.

Very good with them. Being used on a MPCNC.

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

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!

I bought these to use in DIY tools with parts I’ve made on a mill or lathe. I made the mistake of not reading all the reviews. If you want cheap bearings in bulk, this is a great buy. If you want any kind of quality, keep looking. They came in two packs of five tubes of ten bearings each. Every single one of them has some kind of rust. I didn’t expect any rust. If I’m going through the trouble of hand carving metal on a manual mill or manual lathe to build a tool, I don’t want to use rusty parts. I doubt I’ll ever buy these again. The only reason they got a second star was because of the low price per bearing. I’m sure I can find something to do with them, I just can’t use them in anything I ever want to sell if I want to build any kind of reputation for quality work.

Ive owned many bearings over the years, for many purposes. I didnt leave a review sooner ( I ordered these OVER TWO YEARS AGO) because I figured with the absolute abysmal quality, there was no way the listing/store was still even up. You know those things you order, but by the time you go to review the entire seller has disappeared, seemingly overnight? I expected that of these. Out of a set of twenty of them, I found eight which dont exhibit axial tilt while rotating, like the earths axis is tilted and wobbles. Their axial play is easily perceptible, their axial precision (angular wobble off axis) is ABYSMAL (Id say 2.5 degrees on average?) and they make SO. MUCH. NOISE. IF you need a billion bearings with absolutely no requirement for precision or reliability, buy twice as many of these bearings as you think youre going to need. If you need any manner of stability, quietness, precision, reliability, longevity, or any other positive attribute beyond nonzero weight and doesnt crush easily from the side Id suggest you look ANYWHERE else. Ive been angry every single time Ive had to try to find a usable one for a project, for literally two years. NOTE: Im not joking, I can print bearings which run more smoothly and silently than these, out of PLA, AND they track straighter. No, theyre not nearly as strong, and will crush readily, but these are worse for most of my applications than PLA printed bearings.

This is a really great bearing
