Journal Bearing Material for Seawater Pump
Journal Bearing Material for Seawater Pump
(OP)
I'm looking for an acceptable material for a journal bearing for a seawater pump. Due to the size of the bearing and the radial load, the material must be able to operate at a PV of about 130,000 psi-fpm with essentially no fluid film.
I'm currently using US Graphite Grade 14. My problem is that the material is hygroscopic. Over time, it swells and takes up my pump clearances.
Any help in finding an alternate material would be greatly appreciated.
Thanks,
Eric

A Grade M1610 is used for water condensate vertical re-circulating pumps. The bearing material handles salt water temp 120 deg. Centigrade.
