What Causes Bearing Failures?

Most bearing components are heat-treated to harden the metal. But, the heat-treating can only penetrate so far into the metal. Once the bearing has worn through this layer, rapid and catastrophic wear occurs to the softer metal below. This type of fatigue failure is called "spalling." This kind of damage causes the metal to come off in flakes.
