Tests were carried out to determine the influence of selected parameters under designated working conditions on ball bearings friction torque. Such parameters include roundness outline and waviness of inner and outer raceways/rings, as well as curvature ratio. In the case of operating parameters, speed and axial load were taken into account. The research presented in the article shows that these parameters have a significant impact, mainly in the case of low loads and medium speeds, and that the parameters of the inner raceway have a much greater impact on the final result of the friction torque than the parameters of the outer raceways. The studies presented below are part of a larger study aimed at creating a mathematical model to determine the theoretical values of the friction torque in rolling bearings.
