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

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.

Muy bueno

I found these looking for some cheaper bearings to use for fidget spinners and other 3d prints. They do not spin well at all. I dont know if I got a bad batch or if these are just not good quality.

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.

Price cannot be beat. Not even my Chinese contact could come close to this (I could only get 10 overseas for this price). I have yet to test durability, but there are reviews of this product on that and I wont be using them in a manner that could wear them out.

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

These bearings are not hardened as advertised. Upon disassembling, the bearing races and even bearing balls were not hardened and could be easily deformed with slight pressure between pliers and were also easily filed with low grade carbon steel hand files. The wobble was also significant, with the inner shaft and outer being able to skew in excess of 4 degrees without load. The seals were also garbage with holes and flashing still present, but that of lesser importance. Perhaps a more telling sign is the warning in the photo: Note... not professional bearings. That is, these are not bearings any company would use in a consumer product. Because they are not precise, wear will increase. Because they are not hardened, they will easily abrade away. The thick grease is likely there to disguise the rough texture of the races and the already malformed balls. If you use these bearings, do not do so in an expensive piece of equipment or in a skateboard where a bearing failure could mean a trip to the hospital. Go ahead and drop the same amount of money on 6-12 good bearings from a reputable source. If, however, you are going to make a fidget spinner, go nuts. Thats about the only use where quality is of second concern.

Used product for various projects, and liked that there were lots of them for cheap.

these are the worst bearings ive encountered on amazon as of yet, the price really was too good to be true. they arrived super sticky as if they used sugar water as a lubricant. they also require many pounds of force before they even roll. do your self a favor and do not buy

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.
