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)

Came quickly and just ad described, durability is something Ive have to see. Size aas correct as well.

I used these bearing to repair some Adult Assistance Walkers, for the elderly people that reside at the Adult Foster Care/Assisted Living facility, where my wife works at. They were going to throw them out, because the wheels were wobbly. She figured that I could probably fix them & save them from going into the dumpster. These fit & worked perfectly! I was happy & pleased with the quality of the bearings, especially for the price. Be sure to check the size bearing that you are going to need for your application or repair. As they do come in very many different sizes. I must add...Shipping was Super Crazy Quick for these too! I was able to repair 3 walkers with this bearing package/kit. I made the Senior Citizens at the facility very Happy! Being able to use Safe, Smooth Rolling Walkers again. I was a Hero in my wifes eyes...even for one day...so, Ill take it!

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.

They seem loose and wobbly and many of the shields protecting the bearings from dirt are dinged up like they were installed by hand by someone in a hurry. A bearing should only spin and not move in other directions. I plan to use them for wheels on parts bins, so theyll work for that, but I wouldnt bother with them again.

The bearings I received were corroded (ok, they are carbon steel and not stainless) and felt greasy. Grease should not be leaking out of these things, even if they are merely shielded and not actually sealed. They were also rough to turn, as though the races and balls were badly pitted, or had dirt inside. I started to wonder if they were actually used, and salvaged from old skateboards. Thank goodness Amazon takes returns. I ended up buying a different bearing for 2x the price, still very cheap, and a much better product. Don’t waste your time with these.

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.

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.

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.

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