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

The dimensions are WAY off. Pressing these in was more like dropping a toothpick into a volcano. Luckily i dont need a press fit for my application, so it didnt matter. You really get what you pay for here. Also the race was PACKED with FOD. So much aluminum or steel glitter is packed in with the bearings, it feels like sand when you move the bearing around. Only two out of the pack where smooth. This is real bottom of the barrel stuff, but its also literally the cheapest i could find. Im pretty sure the oil that was covering them was some kind of caustic nonsense and it made my skin red where it touched me.

They wouldn’t last long if using them everyday They are not like USA or German bearings

Delivery is quick, as expected from Amazon. When I opened the bearings there was a rancid smell that came from the bearings. That indicates that the grease has run pass it life. When I try to spin the bearing it was not smooth. When I touch the bearing, there was a sticky feel to it. I may have gotten the old bearing instead of their newer ones.

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.

I used these bearings in a 3D print project and they are exactly what I wanted.

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..

Everything is great as far as value for the money and thickness. One thing that could improve is the movement. Doesn’t spin as easy as I thought it would. But I’m also not a pro when it comes to bearings.

These are a great value and very easy spin. Perfect for a new roller for my 3d printer filament

I used these bearings for some 3d printed projects and they work and fit perfectly

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.
