Bearing preload: What is it and why is it important? | …

11/6/2019· Angular contact bearings that are manufactured in matched pairs are referred to as duplex bearings. Duplex bearings are manufactured to be stack-mounted with the bearing faces adjacent to each other. The raceways of duplex bearings are slightly offset but come together when the proper preload is applied during assely.

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.
