Well the one's I have used have had either a grease fitting or no grease
fitting.
I never found anything to inject grease into the ones with.
So the only way to lubricate them was to clean then and use a small
paint brush to apply engine oil to them , this did work up to a point ?
the oil took microscopic grit into the bearing and they ground
themselves away !
Once vertical play appeared between the hard spherical part and the
bronze looking part there was no way of adjusting this play out so the
pivot just got looser and looser.

Yes, a cartridge BB is a good choice. Mine is at least 60.000 km in service - no play so far. And I took it from a scrap bike, which means that it was already old when I installed it!
I always thought, that rod end bearings are quite sturdy. Why did they wear out so fast?
Cheers,
Jürgen.

Hi all
After suffering rod end bearings for the last 4 years I want to move to a BB pivot.
However I am unsure how you make it adjustable so you can ensure the tapers are well bolted up to stop the BB rattling between the pivot anchors [ being either pedal cranks[ original design ] or a built up *[* shape ? ]]
