The rolling bearing is the key element of the space mechanical moving components, which is usually preloaded by application of a pre - selected internal axial load. But the need of the adjustable bearing preload is required due to the multiform load cases in the bearing service life. This paper describes a way to modify bearing preload in - orbit, which can provided hard preload for launch and soft preload in flight to achieve long lifetime of rolling bearing.
