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

I thought hardening at the very least a requirement for roller bearings. I guess thats what I get for ordering chinese crap. Save your money.

Ordered the 100 pack and only received 50. Without hesitation they sent me another order of 100 as soon as I messaged them. Definitely buying more soon, Im a 4th generation roller rink owner and these work great in the rentals after a good cleaning and some white lithium grease.

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

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.

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.

Not bad for the price

Inside hole was a little larger than a previous set overall they worked good for my use

side seals are plastic and some are a bit deformed and interfere with the balls. About 1 every 15 or so are like this

Don’t spin as freely as I would have hoped ended up buying another brand to be able to do what I was trying

there is an incredibly thick grease coating all of the bearings, making them spin VERY poorly. after soaking some in soapy water for 8 hours, it kind of helped, but they seized up again after drying. I used high quality PTFE lube on one, and it still preformed worse than a bearing I pulled out of a trashed fidget spinner without any added lube. Complete garbage.
