Q10. Bearing Shelf Life - What Is The Shelf Life Of A Bearing?

The most important factor for determining the shelf life of a "properly stored" bearing is the lubrication.  Greases and oils do have shelf lives (expiration dates).  This is discussed in detail in our white paper entitled, "Bearing Lubrication"and additionally in our article entitled, "Shelf Life of Bearing Lubricants."

Otherwise, providing the bearing is stored poperly (typically in its original factory packaging), the potential effects of contamination and oxidation will be minimal and not significantly effect shelf life.
