Tonmp 100 PCS 608-ZZ Ball Bearing - Double Metal Sealed Shielded Miniature Deep Groove Bearings for Furniture Wheel,Skateboards, Inline Skates, Scooters, Roller Blade Skates (8mm x 22mm x 7mm)

I have many projects for this product...

Bought 200 of these. Briefly looked at all of them when they arrived. Three had obviously damaged seals. One was damaged enough prevent smooth rotation. Clearances are sloppy, but I didnt attempt to measure that. Seem to be a good value for non critical applications.

Great bearing for a replacement part on a Grizzly G0555 Bandsaw. The price is better than ordering from Grizzly.

If youre using these for skateboarding or something else that puts them under heavy load WD-40 will probably ruin them, but for 3D printing if you give the bearings a quick shot they loosen right up.

Must clean and use lite oil..

I am pleased with my order and is a great deal. So far, I found one bearing a bit crunchy and will try to clean it. Bearings will be useful in my projects.. thank you.

Picked these up for putting into 3D prints. I am using these bearings in low stress environments so I cannot comment to how they will perform in heat or high RPM uses. This cheap 50 pack is working well in my custom spool holders for my 3D printers. I have replaced the stock spool holders in my Anycubic Mega X, FLSUN Q5, and Creality Ender-3 with spool holders that use these bearings and they work fantastically.

The quantity is large and the price is cheap, but I don’t know if it can be transferred at high speed

Product was packaged in two little containers ideal for storage. It’s exactly what it says it is 608 bearings can’t go wrong at this price

Having been bitten by inconsistent measurements in the past (with other types of components), I measured one pack of 12 and found that the inside diameter was between 8.05 and 8.10mm, and the outside diameter was between 21.92 and 21.98mm. Id say these safely have a tolerance of 0.1mm, while my 3d printer typically has a tolerance of 0.35mm, so these should work pretty well for me and not significantly impact the tolerance of my builds.
