The spacers don't place any increased stress on the bearings. To weight of the truck bearing down on the bearing is the same either way.

Lets clarify spacers VS adapters; Spacers are exactly that, a plate with holes in it. An adapter bolts onto the existing studs and has it's own separate set of studs.
Spacers should NEVER be used, and in fact are illegal here in Ontario Canada.
Adapters should only be used in the rear and never on the front. The problem has nothing to do with bearing stress, but what it does is change front end geometry, specifically scrub radius.
I machined my own adapters for the rear of my Blazer ( 1.5") and it made a huge difference in the way the truck looks going down the road.
Be careful of cheap Chinese adapters !! They are a cast piece machined to look like billet stock, and they use very poor material.
