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

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.

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!

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

VERY Noisy and Rough. I seriously question the ABEC-7 rating. I got these because they were low cost, and you get what you pay for. As other reviewers noted, they come in plastic tubes of 10, and are coated in sticky grease. I wiped them clean, flushed them thoroughly with PB Blaster, 3-in-1 oil, air tool oil, WD-40.... they spin freely but feel very rough and are noisy. Rolling them in my fingers I can feel the roughness and I even go so far to say that it feels like there is dirt inside, they catch occasionally and are that rough. These will probably be a good solution for slow speed applications where noise and smoothness is not a concern. For smoother, higher speed operation, and quietness, Im going to spend a few more $ next time. I have the same size bearings from another manufacturer which were a higher cost, but there is a night and day difference in quality. Ill be saving these for something unimportant and testing purposes only. Nothing I build can accept this poor of quality for more than a brief period.

good price, bad quality,

All Bearings making noise and 2 sets of bearing stuck

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.

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.

I love these for 3d prints! They dont spin forever like a fidget spinner would, but then again they shouldnt. The grease is viscous enough to prevent free/loose movement on the filament holder that I printed. If these spun easily and for a long time, I would have tangled filament! I suppose the grease could be replaced if you need a longer spinning bearing, but you might be better off getting another product.

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