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

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

Purchased a set of these bearings for 3D print related projects that require 608 bearings. All of my applications would never put real stresses on these bearings as a skate would, so I cannot review this as its official intended purpose. For my purpose, I have zero issues. So far, I have printed out a filament spool holder and a filament guide. The bearings are smooth. With the set I received, do not have any issues with them being too stiff or too slick as far as ease to roll.

Im using these for 3D printing in the creation of Filament Spool holders. These are perfect with just the right amount of friction so that they roll nicely. I did not clean the bearings but used as is.

These bearings are smooth and seem fairly well made. Unfortunately the manufacturer used a very thick lubricant — probably a heavy grease — so theres quite a bit of friction and they dont spin for very long. If you want them to spin freely with minimal force, youll need to clean out the grease using mineral spirits or maybe WD-40 and then replace it with a lighter grease or maybe just some oil. Ill probably try a different brand next time in the hope that I find some that dont need their lubricant replaced.

As others have mentioned, out-of-the box these bearings do not spin well at all. Theyre covered in a viscous oil thats most likely there to protect against rust. Just run some 3-in-One Multipurpose Oil through them a few times; this will both clear out the thick oil and lubricate the bearings as well. They seem to be just as high quality bearings as most others.

These came pretty sticky thanks to whatever grease they oack them with, not sure I can actually use these for anything than a filament guide for a 3d printer, like most have said here it seems some cleaning and wd40 goes a long way but jt doesnt make up for it and if you dont own wd40 for some reason then youl have to spend more money on a can of that first before using them.

Great service

Like other reviewers have said, they come packed with some thick grease which is probably fine for skateboarding. If you intend on using them for applications requiring them to freely spin, just soak them in a solvent for a little while, then wd-40. This worked great for me, your mileage may vary.

Used to replace bearings in a rollator walker.

Guys just go to the skate shop. Ik you are looking for a cheaper way to skate, its not worth it. Buy REDZ if you have to but dont do Amazon skate stuff you will regret it. These were very loud, and you didnt get very far skating, but its enough to get you by.
