A method for estimating the temperature (TB, est) of a wheel bearing of a wheelset of a rail vehicle by means of a calculation model (Tbearingestimator). The calculation model (Tbearing,estimator) estimates the temperature of the axle bearing, according to the speed (vtrain) and the ambient temperature (Tamb) of the rail vehicle as input variables of the calculation model (Tbearing estimator), and the temperature of a component of the wheelset, different from the axle bearing but directly or indirectly connected to the axle bearing in a heat-conducting manner, is measured as the measuring temperature (Tmeas) during operation. The temperature of the component different from the axle bearing is estimated by means of the calculation model (Tbearingestimator) as the estimated temperature (Tmeas,est). In order to improve the accuracy of the calculation model (Tbearingestimator) in terms of the estimation of the temperature (TB,est) of the axle bearing, the calculation model (Tbearingestimator) has a corrective element (Kb) that is used to continuously, temporarily or cyclically calibrate or adjust it on the basis of a comparison of the measuring temperature (Tmeas) with the estimated temperature (Tmeas,est).
