Roller Bearings vs. Ball Bearings - What's the Difference? - Thomasnet

Bearings are designed such that the slight deformation the ball makes as it rolls into and out of the load zone does not exceed the yield point of the material; the unloaded ball springs back to its original shape. Ball bearings do not have infinite lives. Eventually, they fail from fatigue, spalling, or any number of other causes.
