What Is Spindle Bearing Preload and Why Is It Done?

Bearing ball skidding can be a symptom of an improper preload — usually too little. Essentially, it induces an irregular spindle vibration which causes a severe rise in bearing temperature. The ball skidding effect of the bearing increases from a reduced contact area, or by losing contact completely, when at a certain bearing rotation speed.
