1. A bearing ( 10 ) comprising: an inner ring ( 12 ), an outer ring ( 11 ), rolling bodies positioned between the inner and outer rings, one of the rings being rotary and the other fixed, a first module ( 20 ) including at least one set of sensor(s) suitable for performing successive measurements of at least one parameter representative of the vibrations within the bearing; and a second module ( 20 ) suitable for determining a frequency representation of the signal corresponding to the successive measurements, and for obtaining a set of elements(s) representative of the frequency representation as a function of that frequency representation, so as to compare at least one representative element of the set with a corresponding reference element and identify a malfunction as a function of that comparison ( 10 ).
