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

They seem to be gritty when turned.

They seem loose and wobbly and many of the shields protecting the bearings from dirt are dinged up like they were installed by hand by someone in a hurry. A bearing should only spin and not move in other directions. I plan to use them for wheels on parts bins, so theyll work for that, but I wouldnt bother with them again.

All Bearings making noise and 2 sets of bearing stuck

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

They work and they are working well. That, along with a great price makes it a great buy.

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!

Kind of trash and hardly worked. Almost all failed with a roll pin installed.

They pretty sticky out of the box but thats just because theyre packed with grease, a quick spray with some simple green followed by some compressed air and some oil frees them right up. You could skip all that and just blast them with WD-40 but I like to use actual bearing oil. That said, the tolerances are actually kinda terrible, they have quite a bit of slop in them and they feel rough when you spin them. I suspect thats why they over grease them, to hide the bad tolerances and low quality balls/races inside. I dont use them for anything load bearing or fast speeds, these are just used for the filament roller guides on my 3d printer.

If you have 608 bearings for guides these are great and priced right. You can replace every year for a very cheap investment.

Came quickly and just ad described, durability is something Ive have to see. Size aas correct as well.
