A process for determining the prestress of antifriction bearings which are preloaded against each other or installed with an initial stress, and permitting a reliable determination as to the prestress actually present in the bearing. The initial stress is determined in connection with the elastic behavior (elastic deformation) of the bearing, by first, applying a first force F1 to the bearing as it rests on a flange or bearing ring, and measuring the elastic deformation S1 resulting therefrom. Second, another (higher) force F2 is applied to the bearing and again the elastic deformation S2 resulting therefrom is measured. Thereupon, the difference between the elastic deformations (S2-S1= DELTA S) is determined and the existing initial stress is found by comparison with the elastic characteristic (calculated or empirically determined) of the bearing.
