Bearing Technical Information: Preload
It is important to appropriately choose the preload amount and preload method according to the application! An introduction to bearing preload.
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, which reduces vibrations and noise during rotation, and also increases the rigidity of the bearing.
