A roller bearing assembly for determining loads on a roller bearing includes a roller bearing having coaxial inner and outer rings and an axis of rotation, and a plurality of rollers each having a rotation axis being arranged between the rings. At least one ring has recess for receiving a force-measuring pin. A force-measuring pin is received in the recess. The longitudinal axis of the force-measuring pin extends at least partly along the axis of rotation of the roller bearing. The recess and the force-measuring pin extends into a region, which is under a load, of the ring that has the recess such that at least one vertical projection plane perpendicular to the rotation axis of the rollers extends along the force-measuring pin and a region of maximum load. This allows loads to be reliably measured.
