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.

another one, cam bearing for??

Seems unlikely that style bearing was in a tractor (maybe some early models I'm not familiar with). The "K" suffix numbers were common on harvester-threshers.

300-H is probably a part number from whoever produced the thermostat.

32282-DDR was used in 14- and 18-Series engines.

Another, Liner O-rings? For?

First one is similar to ones in our running gear
from early 1950s. The wheel bearings were rollers,
& had 2 of these sleeves in each hub.
Could fit other units as well.
