Abstract: Various embodiments of the present disclosure are directed to devices and methods for monitoring service life of an installed rolling bearing. In one example embodiment, a methods is disclosed wherein measurements are recorded in a region around the bearing using at least two sensors, and remaining service life is calculated. The step of calculating remaining service life includes determining at least one transfer function, and determining, using the at least one transfer function and the recorded measurements of the at least two sensors, at least dynamic loads on the rolling bearing.
