Help identifying parts

[WD40]

I'm having some trouble finding what some parts are for, I can find them on the inter-web but sometimes doesn't say what they fit. Any help would be appreciated.

First one is a roller bearing 21-946K

On second one is model on box the model of tractor/engine it fits or is that a part #?
Thanks, there Will probably be lots more questions.

That's for a long flat looking roller bearing there will be about 6 little rollers, about 1//4 in dia and the widith of that sleeve. Like some of the older pull type swathers , or in a auger wheel brgs, that were made in the fiftys, that's where i have seen em anyways.

Your roller bearing sleeve (have not checked "where used") was used (if the correct size) on IH wagons and on the front steer axle of a rubber tired horse drawn manure spreader.
Two per hub with two caged flat roller bearings that ran directly on the spindle on the ID and ran on the sleeve on the OD.
Have an IHC wagon that uses that design.
