It is important to appropriately select the preload amount and preload method according to the application! Introducing preload for bearings.
This document explains the "preload" of bearings. When two bearings capable of receiving axial loads are installed as a pair, and a predetermined axial load F (preload) is always applied, this is referred to as applying preload. Bearings have internal clearances, but by applying preload, this clearance is eliminated, and the balls and raceways make elastic contact. As a result, the bearing is free from play due to clearance, reducing vibrations and noise during rotation, and increasing the rigidity of the bearing.
