Babbit? I could be wrong, but as I recall (its been a while),the turbine
and shaft bearings for propulsion, and some of the marine diesel
bearings we dealt with in the Navy were lined with a
lead/tin/antimony(?) alloy called "babbit". Newer at that time for some
marine diesel applications were aluminum bearings. The aluminum ones
were supposed to be better only if the oil was kept extra clean,
otherwise the aluminum bearings were considered to be pretty
unforgiving.
