Can you give more information? bearing size (shaft diameter and length) load on bearing, duty cycle or speed of rotation.
Environment is the bearing protected from dust and abrasives.
There may be alternatives to roller bearings.

I'm not sure that I completely understand your description of the problem, but as you're operating fixed machinery (a conveyor) with few start/stops, perhaps you may want to look into a journal bearing.
