Claim 12:
13. A sensorized hub bearing unit, comprising:
a rolling bearing comprising:
a stationary ring comprising:
a first annular element; and
a second annular element coupled to and arranged coaxial with the first annular element, the second annular element comprising:
a plurality of axial spaces angularly spaced from one another and positioned at an interface between the first annular element and the second annular element, each axial space comprising two axial ends that are circumferentially enlarged relative to remaining portions of each axial space; and
an annular groove;

a rotating ring mounted coaxially and concentrically with the stationary ring;

a plurality of pairs of sensors for detecting mechanical stresses fixed integrally with a radially outer surface of the second annular element;
at least one chamber defined by each axial space and an outer lateral surface of the first annular element and positioned at the interface between the first annular element and the second annular element, and
an annular band disposed within the annular groove of the second annular element,
wherein, each pair of sensors is housed within a respective axial space of the plurality of axial spaces and arranged at a respective annular track formed on a radially inner lateral surface of the second annular element,
each sensor of each pair of sensors is housed within a respective axial end of each axial space,
the first annular element is integrally fitted axially within the second annular element, and
each sensor of the plurality of pairs of sensors are electrically connected by the annular band.
