(#95) Bearing Failure Tolerance GD&T Vibration

This episode breaks down how bearing failure is driven by tolerance stack-up, GD&T mistakes, and uncontrolled vibration. Learn how misalignment, improper fits, geometric error, and poor surface finish overload rolling elements and races, leading to heat, noise, premature fatigue, and catastrophic failure. We connect drawing intent to real machine behavior, showing how concentricity, runout, flatness, and parallelism directly affect bearing life and vibration response. Built for mechanical engineers and designers who want to prevent bearing failures by controlling geometry, tolerances, and dynamic forces instead of chasing symptoms after startup.
