Abstract
A roller bearing includes a fixed element and a rotating element. The roller bodies act as a support on the raceway of the fixed element by the intermediary of a contact surface (S.sub.C). The fixed element includes a free surface which is deformable elastically by the forces induced by the passage of the roller bodies during the rotation of the rotating element. The surface has at least one instrumented area whereon is associated at least one pattern of a sensitive material. The said area is delimited axially between the surface (S.sub.1) defined by revolution around the axis of the bearing of the straight line (D.sub.1) passing through the center (C.sub.r) of a roller body deforming the surface and by the center (C.sub.S) of the contact surface (S.sub.C) of the roller body and the surface (S.sub.2) defined by revolution around the axis of the bearing from the normal line (D.sub.2) to the deformable surface that passes through the center (C.sub.S) of the contact surface (S.sub.C).
