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

Nice product.

WayneChicago is right on with his review and the cleaning. I bought some ZZ bearings I thought were compete rubbish (ironically the same brand/seller without knowing) Then I bought some more expensive RS ones, that were nicer, but a lot more. I needed a lot for my project, I saw his review and the comments on cleaning and I took a chance. When I realized the rubbish ones were the same brand, I tried cleaning those first and I was very happy with the results. Heres my observation/experience. Originally I soaked them in WD40 for seconds, maybe a whole minute, but I thought the WD40 would cut that grease. I think with some, probably the ZZ ones I had, the grease hardens and particles become the grit. Soaking for 6+ hours certainly broke down the grease. I noticed 2 ZZ didnt spin as fast as the others, so I put them back to soak. While soaking, I tried shaking them up every now and then, mostly it just sat there. Upon taking them out, I spun them before drying, some didnt spin so great, but got better and better as I spun them. I think longer soaking may have helped, I probably should have let them soak all day. The set I got came in 2 paper boxes. Each box had 5 tubes of 10 bearings. The bearings were all uniform, and generously coated with some grease. They didnt spin very well in that condition, There were no deformities, there were no defects in the lot. My application is fidget spinners, and after cleaning and light oiling they spun exceptionally well. If you need to take them out of the box and use immediately these probably arent for you. Unless of course your application requires the grease. But if you dont mind cleaning and oiling. They are quite the bargain. Just remember if you clean them, do it safely and well ventilated and Im thinking the longer they soak the better. The cleaning liquid I used was dark blue/green after all the soaking.

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

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.

Very smooth rolling. Capable of use with heavy load

The value

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

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!

These are 608RS bearings a good value. At first they were listed as having a nylon bearing cage but, in fact, they are steel. I contacted the seller (a small startup) and they responded immediately and corrected the description. Unlike another reviewer here, I did not find the bearings that I received to be full of grease, though. There certainly was some grease inside. If using these for light loads, like skateboarding, try opening up one side and putting a couple of drops of light oil in (I used silicone oil) and give it a few turns to thin out the lubricant a little. That really makes these spin well. If using these for heavy loads and high RPM, leave the grease in, of course, without thinning. But, if using them for light loads, thinning the lubricant may just do the trick for you.

Muy mala calidad lo que se muestra en la foto no tiene nada que ver con el producto
