Have you looked at using a wave washer? While it reduces the load
factor you can use, if you find one stiff enough to resist the pressure, it
can accommodate for wear of a solid wear surface. You also might look for
preoiled bearings, such as DU bearing or similar, and either make or buy
something that works. That's really good stuff, too, and handles high
pressures really well.
