Do you have any references to work regarding plain bearing materials, eg various phosphorus bronzes, cast iron, babbits etc?

Some data about permissible surface speeds of different plain beearing materials and also PV factors (pressure times velocity).

Some more in depth articles would be appreciated, not just casual "leaded phosphorus bronze is the best".

I apologise in advance, but I am going to go all pedantic here, and mention that it is phosphor bronze, not phosphorus, and Babbitt metal, not babbits (or babbit).

Sorry!

I am always interested to recitative articles on such topics, ideally written from genuine experience rather than just harvested from the net*.

*Not that I have any problems with authors using the net to fill gaps in their knowledge or check facts!

Thats OK, regarding Babbitt metal, I am referring it as "babbits" because there are many similar alloys of comparable composition (tin,lead,antimony,copper are important there but other elements can also be present).

So "babbits", "Babbitts", "white metal" or whatever are just wider term.

Anyway do you have some interesting data regarding these?

I have this book but it is far too little for me. Any engineering books dealing in depth with the subject?

Martin , In that case , are there any suitable downloads available from any of the leading bearing manufacturer's web sites ?

Babbit or whitemetal bearings will run happily at 15,000rpm!

With a dedication like that, what's not to like?
My copy came from the GEC/AEI/Met-Vic library at Trafford park, via Rugby..
