Abstract
Revolution speeds of rolling elements in respective rows are sensed, and then the axial load or the radial load is derived based on the revolution speeds. In case the acting directions of these loads are displaced, the contact angles of the rolling elements in respective rows are differentiated in response to this displacement, or values of influence coefficients used to detect respective loads are changed based on the revolution speeds.
