What do people think? Will rod end bearings with a bronze insert stand
up to continuous use in a rock tumbler if I keep them clean and well
lubricated? Any thoughts would be much appreciated.

How about taking a block of UHMW and drilling two holes in it at
whatever spacing you desire. With a moderate load UHMW will last a
long time and when it wears you can just drill two more holes. If you
have a heavy load you can use nylon for better wear resistance.
