Is the inner race split so that it can be deep enough for the side load support and still be able to assemble it?

Yes. That's exactly it.
Thanks everybody, specially "Ptsg" for sharing useful information.
I didnt mention that I am from Europe, so we only have 25 series but it seems to be 95% same as 20 in US. But that another topic.
I am no hurry with seal replacement, cause I use my tractor very little, specially in colder periods and it will not leak when not in use.
I will educate myself a little on different bearings and their availability. As far as I quickly checked, same size different style bearings are available... as one mentioned I may not have to change the bearings but I want to be ready for that if needed.

My dealer said the DPF+DOC had more catalyst than the 20 series and the front axle was wider or had bigger extensions bolted on. The PTO and cruise control switches were on the fender while the 20 series had them on the dash. Also it came with two rear remotes and a block heater but I think my dealer added those as a way to help differentiate them from the 20.
Some months are gone by... but we got the seal replacement done before christmas.
It was quite an easy operation, althought I didnt do it myself.
The only ??? moment was when we got the hub disassembled and found that new seals dont fit on the shaft. New seal, in factory package, correct part nr was way smaller on inner diameter and also much thicker-beefier than the old one.
Several options were on the table and I almost took the hubs to machinist to take down some material from the shaft but just then my friend who did the repair, discovered there was a thin sleeve on the shaft on witch the old seal was placed.
We got it off the shaft and then new seal went perfectly on.
The sleeve was rubber coated from inside, factory piece. The machinist said he has seen some solutions like this before. Most probably its made replaceable cause the seal may wear some grooves on shaft and it may start leaking. With a thin sleeve, you can replace both seal and the sleeve and the shaft preserves its surface.
Somewhy they dont use this solution anymore and also the dealer didnt mention a thing about it?
Anyway, the new thicker and stronger seal went on and I also replaced the bearings. Some china stuff was in there before, now I put German premium brand FAG. Luckily these are very common bearings, 2+2 cost only 45 $.
2 big O rings and a silicone as it was before and together it went.
No leakes so far but we have winter time with snow and cold weather, we`ll see in summertime when the oil is thinner and tractor gets some workload.
Thanks for everybody for good advice and I will try to start a new topic about my tractor in some close times. Just found out that its super-easy to ad pictures.

Thanks for the update. Indeed the bearings are very common and cheap, even the good ones.
I was just checking some part numbers regarding the seal, since it's the same for my tractor so this post had my attention. Anyway, it seems that the one you got is the new updated seal.
Not sure it's a good change since the new one can wear a groove on the spindle over time just like it was explained to you while the 2 piece seal won't let that happening. Time will tell I suppose.
I'm at around 500 hours and still no signs of having issues with the seals or bearings.

Jep, new seal may wear some groove into shaft surface but my machinist said there is enough room and material to machine future damaged area down, make a new sleeve, hot-mount it on the shaft and machine it into correct size. And it can be done over-and over again if needed.
But I doubt that I can wear this groove in... and I have much more confidence in new, improved design seal. We`ll see
