ABSTRACT:
A method for the determination of the axial thrust of roller bearings under extreme operating conditions, which includes determining the variation in the rotational speed of the bearing cage, and employing the obtained value as a measure for calculating the axial thrust. The method employs sensors, such as strain gauge strips, applied to a stationary portion of the bearing to obtain the cage rotational speed through the dynamic deflection of a bearing weak point formed in that portion of the bearing.
