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

All Bearings making noise and 2 sets of bearing stuck

I ordered these to use as bearings for fidget spinners, I know. These were nice and cheap, and I wanted to give these a go. When they arrived, I noticed a couple had small spots of rust on the inside, so I emailed the company and they replaced them no questions asked and were very responsive and helpful. After decided the rust wasnt really that noticeable, I popped off both shields and then let them soak in gas so it would break loose all the grease (wasnt much). After letting them soak and shaking it a little, I took them out and let them dry. Afterwards, I sprayed them down with RemOil and took them inside. In a pretty light spinner, theyll spin for about a minute! I prefer these over the Bones Reds, simply because they spin longer and theyre cheaper. Overall, great product for the price and great customer service!

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

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

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.

packed with sticky grease to make the bearings appear more precise. Once you remove the greese with a good degreaser (major effort) and replace it with a light oil you notice a lot of play in the bearings dimensionally. If your just looking for a cheap bearing that spins fast then these will do. If your using these for any projects that require some accuracy on center of bearing look elsewhere.

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.

Purchased these for use with my 3D printer, filament spool attachments. These worked great. Nicely sealed, lightly oiled and in a nice reusable container.
