Influence of bearing preload mode and speed There are two ways of axial preload of bearing, one is constant pressure preload, the other is positioning preload. Under constant pressure preloading, with the increase of rotating speed, the radial stiffness of the bearing increases slightly, while the axial and angular stiffness decrease rapidly. Under positioning preload,…
