Angular Contact Bearing preload - Practical Machinist

21/11/2007· I use Barden ABEC 7 angular contact bearings for Mitsui grinder spindles.I use HDL fit which is a light preload (.00035 per bearing).Grind all spacers to same thickness,for each individual bearing. Then i grind another .0002 off the inner spacer.This gives me a total preload of .0009 per bearing.Make sure you clean all parts and tools before assely.Do not …

3 Things That Change a Ball Bearing Preload - GMN Bearing USA

Preloading a ball bearing is required for angular contact bearings because they need constant contact between the balls and raceway, which is achieved through bearing preload. The constant contact between the balls and raceway allows angular contact bearings to operate at higher speeds and have higher load ratings than a common radial ball bearing.
