ANCIRS 20pcs 608-2RS Ball Bearing Double Rubber Sealed Miniature Deep Groove 608rs for Skateboard Inline Scooter Roller Blade Skate(8mm x 22mm x 7mm)

I got these to make a yarn swivel spool for my yarn cakes. These work well with no modifications, but I decided to clean out the factory oil and put wd-40 in. With the wd-40 these suckers spin freely and it's marvelous.

The 20 bearings that I received were adequate for my purpose. All were cosmetically adequate and the seals look to be "sealing". All 20 fit over my 8mm shafts and run smoothly. They are lubricated with a grease so there is some drag but that's not a problem for my purpose. I think they are good value for money. I'm about to order another lot and I hope the quality of those is equal to the first lot.

Great for 3D printing projects.

It's solid and works well. Fits to a 3D printed mold pretty well. However, rotation is not the smoothest. May need to dip it in a grease or lubricant to get the best performance. For what it is worth, pretty good.

Used these to repair wheel on my dad's walker....fit perfectly...smooth and have extra to rebuild the wheels next time.

So, my standard workflow when receiving new ball bearings is to take them out of the packaging, test them real quick and then place them directly into a lubricant bath (in a sonic vibration device to make sure the lubricant gets into all cracks and crevices). This is THE FIRST TIME, however, that the bearings rotated so smoothly out of the box that I didn't feel there was a need to add any additional lubricant! That's pretty impressive because I go through bearings like crazy (using them for my own designed parts) and I've tried probably about 50 different brands and models of bearings so far. Almost all of them could use some extra lubricant... but not these. Very impressed!

These bearings are smooth and feel solid. I used them for 3D-printed spool holders and they made all the difference in the world! Even my wood filament that I had issues with before now rolled off smoothly and printed better than ever before. Great quality items!

Using this In a filament rewinding jig and they work perfectly. They spin freely and smooth.

Bought them to update some roller skate wheels for my roller derby team and they've held up well!

I bought the 20-pack of 608-2RS Ball Bearings and have been very impressed with their quality. Designed for skateboards, inline skates, and scooters, these bearings (8mm x 22mm x 7mm) fit perfectly and were easy to install. The double rubber seal is effective in keeping out dirt and dust, ensuring a longer life and smoother operation. They've significantly improved the ride quality of my skateboard, offering a noticeable difference in smoothness and speed. Great value for a pack of 20, these bearings are ideal for anyone looking to upgrade or replace their equipment's bearings.

ممتاز

I used the bearings for a sander and they were very good

They are good bearings but could be more free moving. Not the best for fidget spinners. But still good if you print the spinner in 100% fill so you can get some good spin going :)
