  • Bearing preload: What is it and why is it

    2010-9-15 · The point of my post is that on the spindles I refer to, both 'cones', the bearing element, are pressed or shrunk onto the arbor in a light interference fashion. They face out from each other. The 'cups', or races are the items captured by the spindle housing. Adjusting a preload nut squeezes the cups together onto the cones.

If the bearing outer ring isn’t constrained in it’s housing the outer just expands, giving you a fake reading.
