Need help to choose a pallet jack load wheel bearing

[Superbowl]

A while back I picked up some random new/old stock pallet jack load wheels. I want to use them on a project (not on an actual pallet jack.) I thought it would be easy to figure out what bearings would fit inside them but with out knowing what brand/model pallet jack they were designed to fit, I can not figure out what bearings to use. The inside diameter is stepped. Two photos show the diameter of the first two steps. The third photo is of a tag that was inside one of the wheels. Can anyone point me to a reference showing what bearings will work?

Likely for a Yale jack

Or take it to a bearing supply and see what they can come up with.

If you want to use the rollers on a floor,you need double shielded bearings .....if you quote the OD and width,any number of people here will give you the bearing no.

Why do you say shielded not sealed? I would use sealed pretty much anywhere under 7,500 RPM or so. Unless it is inside a sealed gearbox with oil splashing around.
