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

Bought these for a custom fidget spinner. With the original grease, it spun around twice. Two rotations. I removed the dust covers and grease and they worked much better (though obviously dont do that on a skateboard)

They work. Theyre decent quality but from what I could tell, not for high precision applications. The center bore wasnt always exactly centered and several spun rough but did work and will be sufficient for my needs. Id guess these were pulled from old equipment as many of the ones I received showed signs of previous external wear. I also had to clean these up as they were sticky to the touch, smelled awful and were initially very difficult to spin.I soaked half in Mineral Spirits and the other half in Acetone. Both methods seemed to clean these up really well and they all spun freely after cleaning. Ill likely repack with better grease when Im ready to use these. For my project, im more interested in lowest possible resistance and not concerned with speed or

Picked this up for a spool holder and they worked great! Had to spray down with some WD-40 and roll a bit but once that was done they worked great. Have a few more filament guides Ill print that will use this but great for what they needed to do.

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.

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

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.

Good bearings. I have used these in a variety of 3D printed projects. They exhibit a little more friction compared to the bearings found in fidget spinners, but they will last much longer I am sure.

Pros: - Cheap - Comes with shipping oil to keep out any grit/grime Cons: - The QC is awful I purchased two packs of these to use for a project and found that 10 of the 40 bearings had issues. Many were minor such as small dents/dings in the shields, but there were a few where the entire inner or outer bearing piece has been chewed to bits. If youre going to buy these, make sure you buy extras since about a quarter of them might be faulty. Since this was fulfilled by Amazon, Im unable to contact the seller for replacements and dont want to return the rest. Still three stars though, you get what you pay for.
