Abstract
A roller bearing includes a stationary member, a rotary member and at least one row of rolling bodies arranged between the members so as to enable their relative rotation. The stationary member includes a circumferential surface that is resiliently deformable by the forces induced by the passage of the rolling bodies when the rotary member rotates. The surface has at least one instrumented area on which at least one gauge for measuring the deformations is attached. The instrumented area is circumferentially surrounded on each side by a non-instrumented area, and the rigidity of the instrumented area is strictly greater than the rigidity of the non-instrumented areas.
