    It works acceptable, but the lubrication used was gummy and sticky. The packaging was just a plastic tube that doesnt really seal which wouldnt be a problem if they used better lubricant. I havent used them for any demanding tasks, but they work for random projects

    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.

    Used to replace bearings in a rollator walker.

    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.

    Currently using one as part of a 3D printed stabilizer for my Z-axis on my Ender 3. Its the perfect fit allows rotation and little wobble. Printing has been going a bit faster and cleaner.

    These bearings worked for what I needed them for (filament spool rollers). They were sticky at first but as other reviewers pointed out that was easy to fix. What cant be fixed is the variability of the tolerances. The diameter of the inner hole was inconsistent even on opposite sides of the same bearing. A few of them also came with the metal shields smashed. They can be removed pretty easily bit if you need them to be shielded I would look elsewhere.

    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.

    I bought these to use for 3D prints instead of skateboarding, so my review doesnt necessarily reflect their intended use. Ive noticed for about half of these bearings, they tend to bind up and stop spinning at lower speeds. And they dont come with any greese or oil in them as far as I can tell. Ive sprayed silicone lubricant in them and that seems to make some of them work better, but most of the problem bearings still bind up at low speeds. They all function, but if you want extremely smooth and reliable bearings, Id suggest you look somewhere else. They functioned just fine for my project, but I think the quality control could be better.

    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.

This 608ZZ shielded 8x22x7 miniature ball bearing is a single-row bearing for supporting radial loads. The bearing is made of carbon steel for durability and resistance to deformity under heavy loads, and is shielded to keep lubricant in and contaminants out.
it has a revolutions per minute (RPM) limit of 34,000 with grease lubrication. The dimensions of this bearing make it suitable for use in skateboards, inline skates, and scooters, among others. These bearings come in a pack of 20.
Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or
tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The
shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics,
dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.
