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)

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

As described

I have many projects for this product...

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.

They do spin, but dont spin well for my use, a couple came squished and dont spin at all

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.

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.

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.

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.
