yes, but still a weakest link situation, if one point can take 3000 .... that's the limit, regardless of what the rest can take - think about it, block one side up on a 2x2 and the other side on a 4x4, will one will break first?
I think the change to tapered roller has more to do with the disc brake physical design arrangements due to the load being carried further out, not any inherent superiority - some very high end cars still use ball bearings, and all the newer bearings I've seen for our applications are now sealed and plastic caged, very high tech stuff
folks do seem to recommend changing to rollers with discs, but the B45/46 [slightly different dimensions] work fine and are the called for bearings for the trucks - not sure if there's a difference for a 3/4T AD, but the ones in my TF 1/2T have been working for years of daily use [drums brakes]
