Donepart608RS Ball Bearings, ID:8mm x OD:22mm x Width: 7mm, ABEC3 High Speed Double Sealed Bearings for Skateboard, Inline Skates, Motor, Wheels, Fidget Spinners, 3D Printer (2 Pack)

When the time came to buy bearings for my MPCNC project, I accidentally bought shielded bearings from another cheap supplier on Amazon instead of sealed ones. And boy am I glad I bought extra! Most of the bearings were scratchy and almost all had at least some lateral slop. I had to completely discard 15% of them. Absolute trash. You get what you pay for, right?Not so fast! Since I was switching to the new design, I decided to get sealed bearings this time. Since the other supplier has such terrible bearings, I thought I might as well try another. These bearings were about 25% more expensive, but that was still hilariously cheap. And the quality is like night and day. The bearings are packed with a thick, but not gluey grease that gives a great smooth feel as they turn. None I've tried have had more than a whiff of scratchiness, and NONE have had any obvious slop. Picking them at random, I haven't found A SINGLE bearing that I need to discard. They all feel MUCH sturdier, smoother, and all around better than the last set. Just an all around higher quality.If you need bearings that spin for hours, or are sub-micron precision... You shouldn't be looking at 25¢ bearings. If you want a whole bunch of *totally fine* bearings at a great price, these are a fantastic deal.

Manufacture gives you a parts breakdown with their drain cleaner. Then refuses to sell common wear parts and says go find one of their sellers for parts. The sellers of the "feed rollers" (bearings) wanted $40 to $55 for three of these bearings. They are the same bearing as these that I just bought 100 of for $20. All bearings came wrapped in plastic tubes, in packs of 10. Should give then a pretty long shelf life.

I use these for mechanical sculptures with moving parts. Great price for bearings. I haven't used them in a skateboard so can't vouch for their quality for riding, but they work well for what I'm doing.

Worked well for light duty application in a 3D printed part. Accurate size. 4 star only due to rolling resistance due to grease on inside. I removed the black gasket and used brake clean to remove the grease.

Handy for a number of projects

Having bought 100 packs of 608 bearings before, I'm always amazed that you can get precision metal ground into useful bearings for fractions of a dollar/per. So a little stickiness and cleanup never bothered me much for such a useful prototyping part. But these bearing were the nicest and cleanest batch of bulk 608s I have bought yet. Good deal for nice clean, cheap bearings.

With these new bearings, I was able to complete a project. I made a new filament roller from one real to the other.

A simple fix for a failed motor bearing in a Ridgid shop vacuum.

Price point is great. Quality was there. Seals are good fit. Bearing spins well. Works great for slow speed applications. Would still step up to a higher quality bearing if was for high speed or high precision.These are excellent hobby use bearings at a great price.

Excelentes rodamientos con tapas de neopreno para poder lubricarlos

it came packaged 10 per tube working good on my cnc

They immediately stop when you try to spin them even if you clean out the grease and replace it with a lighter lubricant. useless. I really had my hopes up after buying other bearings on amazon and seeing the reviews for these ones but these are just as bad.
