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

Had to clean with WD-40 but after that they all spun freely no problem

I am not using them as they are intended to be used. I am over speeding the bearings. But they are holding up

I bought these to replace old bearings in my bandsaw guides. They work fine, though I did have one in the package with substandard machining and you could feel friction when spinning it. I tossed that one and the rest were good.

I used these for demo motors to show kids how things work. The first thing I did was pull the grease covers (shields) off and wash the bearing with acetone to clean them. Be aware that the set that I purchased did not come packed with grease, which for me was great - less cleaning. I want the kids to see how the bear works. The great thing is that still today after thousands of rotations and hours of running time, none have failed.

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.

very good for my job

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.

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!

This is a very high quality bearing. As others have stated, its got a good thick lubrication applied. Out of the box, they are perfect for heavy loads. For most tinkering and crafting where you want as little friction/resistance as possible, youd probably want to heat these a little and get rid of that lube to install a lighter weight lubrication. Other bearings might spin better out of the box, but the quality will probably be lower. Id recommend these bearings.

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.
