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

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.

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.

These came pretty sticky thanks to whatever grease they oack them with, not sure I can actually use these for anything than a filament guide for a 3d printer, like most have said here it seems some cleaning and wd40 goes a long way but jt doesnt make up for it and if you dont own wd40 for some reason then youl have to spend more money on a can of that first before using them.

I did not use these in a skating application. I can not speak to their durability in that application. There were used in a spooler that required a set of 608 bearings that could simply roll smoothly at low speeds. All dimensions were within stated specs for 608 bearings. They come pre-greased in tubes of 10. No complaints and would order more for additional projects.

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.

Two out of 20 are very rough and poorly made. Quality control is questionable. All bearings needed break-in to spin. About 5 spin well, rest are just mediocre.

These are nice bearings, but despite the positive feedback, DO NOT use these for fidgets. I bought these so I could 3D print some spinners and resell them but these were just spinning disappointments. I gave 4 stars because this is advertised for skating, not fidgeting.

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.

I got the bearing to use for the 3d print parts, but out of the box the bearing does not rotate too well. You may need some clean up and re lubricant depends on the use. Overall its OK for basic use.

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!
