how to calculate the wall thickness for a journal bronze bearing

[pphawk]

Hi, I can't find how to calculate the wall thickness for a journal bearing. there is a lot of information about the allowable pressure, but for the thickness, there is no information. Can you give some information about it? TKS

Plenty of missing info.

A one piece bearing/bushing ? See what is commercially available.
Two half shells ? Retained by housing "crush" or pins or similar features?

Note there are many flavors of bronze. Some require excellent lubrication.
The leaded bronzes are more tolerant of skimpy lube, but "weaker."

Typically it depends on what the bushing can withstand if you are pressing it in.
I base my tolerances on a FN3 Force fit.
If your heating or freezing you can go pretty thin but you also have to consider how it is going to react to things like the lathe jaws.
To thin and you get a 3 or 4 sided bushing.
