It would only touch the rear one if too much pressure is applied rather than letting the blade cut without forcing.

I'm not sure that that is the case. The gap is supposed to be set at the thickness of a £5 note which means that the blade is always going to touch that rear roller when it's cutting - unless it's a massive resaw blade and tensioned to within an inch of its life.
Regarding life of these bearings...given the amount of run time that the bandsaw has, maybe a few hundred hours if that, then if wear was a problem then surely most cars would be immobile ? Maybe the bearings are cheap'n'nasty and not sealed very well and fill up with sawdust?
