BZlamp 608RS 10 Pack Deep Groove Ball Bearing, Black Rubber Shielded, 8 x 22 x 7 mm Replacement for Scooters Roller Skate Longboard 3D Printer RepRap Wheel Skateboard Bearing ABEC-7 Grade

The whole point in getting ball bearings like this is so they are free of friction, and really smooth. These are far from that. I had to soak them in oil to get them to be smooth.

Exactly as described. I did have to lubricate them to loossen them them up more. Like they had ben sitting a while. But They are working great!

Cheap ball bearings with nonuniform or proper fitting seals. Would not use in anything hard to replace it with high loads. However perfect for cleaning and greasing out of the box and using on little to no load uses like 3D printer accessories.

I used these on my band saw. They fit perfect and work great. Can't beat the price!

good price

Inside diameter was too large, had to use a shim. Bearings failed to last a week in my sander. Save your money unless you plan on light, light use. My application was a se430 mini da sander bearing closest to the 3" sanding pad. Went ahead and ordered

The inside diameter of these bearings is too large by .0015”, therefore, if you have an application that requires a “tighter” fit, I.e. guides for a bandsaw, you better look elsewhere. These were unusable for my application.

Buy these if dimensions and quality don’t matter. Otherwise avoid at all cost! Inner bore is .015 - .020 bigger than they say and they are made of what seems to be lead

The "seal" is not rubber. It's a soft, brittle plastic. They do not seal at all, you can see the balls under it.
