The Influence of Preload on the Work of Angular Contact Ball Bearings [PDF]
Archive of Mechanical Engineering, 2016 Abstract Optimum values of preload can be achieved in well-tried constructions and then applied in similar structures. For new structures, it is recommended to calculate the preload force and to test the correctness of calculation by means of experiments. In practice it may be necessary to introduce corrections, because not all real work parameters can
