Film Strength

Glossary Term

Definition and Purpose

Film strength refers to the capacity of a lubricant's film to withstand pressure without rupturing. It is a critical property that determines the lubricant's effectiveness in preventing direct metal-to-metal contact under varying conditions of load, speed, and temperature. High film strength ensures that the lubricant maintains a protective layer between moving parts, reducing wear and extending equipment life.
