Many applications place stringent requirements on the compressive or tensile forces provided by the springs. For example, the bearing pretightening force provided by the spring must be kept at a reasonable value, the bearing pretightening force is too small to play a role, the friction force is increased due to the fact that the bearing pretightening force is too large, abnormal sound of the bearing is caused, and the service life of the bearing is reduced.
