Sackorange 608 ZZ Skateboard Bearings, Double Shielded,8x22x7 Miniature Ball Bearings（Pack of 20)

very good for my job

I typically buy these else where and this is my first purchase with this Vendor. Typically I get 608s and they are well lubricated but, also feel very clean and resistance free. These however were VERY lubricated and almost to much to where it was hard to clean. They also did not spin as freely as one normally does that I am used to. Perhaps a bad run.

Not the smoothest bearings Ive bought but these are cheep and do what I need them to

I bought these to use for some 3D prints. They are skateboard bearings, so they come pre-greased. I would have preferred to have non-greased bearings, but it makes sense that they would be greased.

They seem to be gritty when turned.

These are labeled as 608ZZ and are double metal shielded. The ability to spin freely is somewhat limited for some reason. I dont know if the grease inside is too thick or what, but if youre looking for a bearing for a fidget spinner then you might want to look elsewhere. On the other hand, there is no play between the inner race and the balls and outer race, so I cant say they are sloppy loose either. I think they are a god value for the cost as long as you are not wanting something that is going to spin freely for any length of time.

These are an exact fit bearing for the FL Sun cube 3D printer I had. Unfortunately the quality, although better than the originals, still included ones with defects. I replaced the four bearings and found that three of the four had bad spots in them. I sorted through the first package of ten and found that 4 were bad, with a spot that clicked when the shaft was turned. Of the six remaining, I chose the best four and they are currently working fine. Note. These are NOT sealed bearings and do leak lubricant. However, because of this, they can be flushed and re-lubticated. I do not recommend them for Inline skates or any machinery that is precision, critical, or may be exposed to contamination such as dust and dirt. They are low cost and low quality. OK for the price, but thats all.

works in a lot of prints for 3d printers. i used to add to prints for a mount for the filament spools and a filament feed guide. greatly reduces tugging and grabbing and i have plenty of extras!

No tienen la medida correcta

Got these for 3d print use, some are definitely smoother than others but for what i needed them for, perfectly fine. If using for a skateboard etc, might wanna seek something of better quality unless money is super tight
