(48 min.)

Understanding K Factor

The wear (or K) factor relates bearing surface wear rate to the variables of pressure, velocity and time. The lower the K factor, the greater the wear resistance. This is a valuable metric when determining what bearing material is right for your application but it's more of an informational tool and many people aren't familar with it. We explain how it works and why it's useful.
