Doing the bearings on driveshaft. I sourced this national bearing nps-100-rpc for the pto side driveshaft. Is this a sealed bearing meaning it will keep the elements out?

IMO, no. It will keep alot of physical things out like sand, etc but not water. We use those bearings for an inside job (like in the building) and relatively clean. For anything outside or in a nasty environment we would use If I remember correctly an RS bearing with the plastic or teflon seal (been awhile).

You want a shielded bearing like you have pictured for both sides. The RS stands for removable seal.

It shows rpc, not rs. Same thing?

The issue we had with that style of bearing was water would infiltrate and the outer “seal” would rust out since it is metal. We ended up going with these

We got less water infiltration and no rust. But for the life me I can’t remember their “identifier” I was thinking RS but that appears to be wrong. This was on big industrial wood processing equipment so it had to keep everything out down to the flour like fines generated when processing wood and being outside also had to withstand rain, snow, 140 degree + temps and down to -50 degrees. Look at Mcmaster Carr. That’s where we got ours for work from and I ordered mine from for the guide wheels on my Vmax which is now gone.

Nothing wrong with that bearing you posted pic of. It’s sealed and prelubricated as noted.
