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

The ball bearings did do what they were supposed to, but didn’t do it well. The bearings were heavily greased to the point of no free spin. With a nice isopropyl bath they end up working for what I needed them for.

I was worried at first because the didnt want to spin, but once I put them on my board, they (for lack of a better word) loosened, it was smooth cruising. Great product..

I had to make a bass string winding machine for musical insterments and these bearings are just what I needed. In the pass bearings like these were in windmills, worleyjiggs I think its what they are called forgive my spelling! Since you cant find them in local stores you have to depend on reviews like these. YES I WILL USE THEM AGAIN. Good luck!

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.

packed with sticky grease to make the bearings appear more precise. Once you remove the greese with a good degreaser (major effort) and replace it with a light oil you notice a lot of play in the bearings dimensionally. If your just looking for a cheap bearing that spins fast then these will do. If your using these for any projects that require some accuracy on center of bearing look elsewhere.

They work as designed and were cheap, used in a 3d printed project.

Like others mentioned, these come packed in grease and nicely stacked in tubes. Once you spray a dab of WD40 on them they spin very freely and the dimensions are accurate from what I can see. I did receive one that was slightly damaged but the rest were all good. I would buy these again.

Purchased these for use with my 3D printer, filament spool attachments. These worked great. Nicely sealed, lightly oiled and in a nice reusable container.

Used on rollators for a 270lbs person. She likes to try to get the thing to turn on the none turning wheels while shes sitting on it and twists the bearings apart. After destroying 3 rollators because I didnt know what part to buy, these make it not matter. Pop out the old one, push in the new one and off we go again. As far as durability, she has destroyed one of these yet going on 8 months. So better than the original.
