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

Good bearings. Slight surface corrosion on outside but none visible under seals. Light coat of oil here and there but no evidence of intentional lubrication inside. Clean, lubricate, and inspect seals before use.

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.

Inner races have very poor tolerances... guess you get what you pay for but I really wouldnt consider these rideable on a skateboard, wheels wobble pretty hard. Very thick grease on them too.

i needed 63 of these to biuld my MPCNC, they seem to spin fine and fit right what else could you really ask for out of a bearing

Three are a bit crunchy but the rest all spin nice after soaking in pb blaster..thx to all reviewers that suggested this. Yet to know how durable So far so good

Yup, they are bearings. But would not give above a C rating for condition, even at this price. Packing was lacking. All just in a big bag. I found at least 3 different labels on the seals so thinking its a mixed batch of brands. Probably why some seem ok and some not so much. Also cleanliness control was lacking somewhere. as several of them have heavy grit all over. Normally would not care that much, but considering the seal is questionable on many of them as well, its likely the grit got into some. Wanted to use out of the bag, not have to clean and re-lube before use. One seal was missing a part altogether, and others have gap where you can see the bearing inside. Would have been just as well to get non-sealed bearings.

First let me say I am a Forensic Engineer, next let me say that I have been in a wheelchair for almost 40 years. With that said, I have never in my life come across a product as bad as these!!!!! I purchased these less than 4 months ago and have had to replace them 4 times due to bearing failure. My application is not even a difficult one as all I am doing is putting them in the front tires of my wheelchair, yet they keep failing. They are cheap but you will spend more money replacing them than whatever you may have saved buying them. DO NOT BUY THESE UNLESS YOU WANT TO REPLACE THEM EVERY 1-2 MONTHS OR LESS.......THEY REALLY ARE THAT BAD.

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 rough rotation. Poor quality. Cheep but was it really worth the savings? No

Had five different 608 bearing types delivered to test for a device I’m building. I’m throwing these away, all 100 of them. These feel like they have sand for a lubricant, and that’s just testing with my finger tips holding and turning the bearing. Under load these will fail quickly. If you need a bearing that will only last 24 hours, this is for you.
