What Is Deva Metal?
Composition and Operating Principle of a Solid-Lubricated Bearing Material
eva Metal is a composite bearing material produced by Federal-Mogul. It operates on the principle of solid lubrication, combining a structural steel backing with a bronze bearing layer and a solid lubricant, typically graphite, topped with a low-friction surface film.
This layered construction allows the material to function in applications where conventional oil or grease lubrication is impractical or unavailable.
