    I needed ball bearings that ran smoothly for my application. These bearings are packed with grease and didnt roll smooth enough for my project. However, I think theyll be ok for other applications.

    All Bearings making noise and 2 sets of bearing stuck

    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.

    They work as designed and were cheap, used in a 3d printed project.

    If you have 608 bearings for guides these are great and priced right. You can replace every year for a very cheap investment.

    They pretty sticky out of the box but thats just because theyre packed with grease, a quick spray with some simple green followed by some compressed air and some oil frees them right up. You could skip all that and just blast them with WD-40 but I like to use actual bearing oil. That said, the tolerances are actually kinda terrible, they have quite a bit of slop in them and they feel rough when you spin them. I suspect thats why they over grease them, to hide the bad tolerances and low quality balls/races inside. I dont use them for anything load bearing or fast speeds, these are just used for the filament roller guides on my 3d printer.

    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

    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!

    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.

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.
