Metcar® M-161 is babbitt impregnated carbon graphite, very low friction, excellent bearing material for use in lubricated or non-lubricated services from cryogenic up to 400 F (200 C). Babbitt is the same metal used for oil-lubricated sleeve bearings (also called “white metal” in some parts of the world.) Babbitt has excellent bearing properties with very low friction and excellent heat dissipation.
Benefits Of Replacing Traditional Bushing Materials With Metcar M-161
M-161 is completely non-galling and non-seizing, making M-161 a great replacement for traditional bushing materials in low-lubricity services such as condensate or LPG. Pumps fitted with M-161 can survive running dry at startup and through other typical process upset conditions which will damage traditional materials. Bearings that originally required oil or grease can often be changed to M-161, eliminating the need for external lubrication. M-161 has a very low coefficient of thermal expansion and excellent dimensional stability for use in all types of bearings, bushings, and similar components for rotating machines.
- Vertical pump shaft bearings
- Agitator bushings
- Non-lubricated bearings
