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)

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

Some are super smooth and some are a little gunked up and probably need to be taken apart and reoiled. But I find them addiquite for my some 3d printed parts I made.

A spray can of white lithium grease is 100% necessary to get them moving. One bad one out of the 20 I lubed. Worth it though considering how cheap this is for 100.

Great product! Would find a way to expedite shipping time!

I have many projects for this product...

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.

Wouldn’t recommended for skating either

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.

As described

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