The rigidity of a rolling bearing is determined by the amount of elastic deformation that occurs when it bears a load. In general, this amount of deformation is small and can be ignored, but in some machinery, such as the spindle system of a machine tool, the static stiffness and dynamic stiffness of the bearing It has a great influence on the characteristics of the system. Bearing people WeChat professional! In general, roller bearings have higher stiffness than ball bearings. Various types of bearings can also improve rigidity to varying degrees through proper "preload".
