In a machine element having a hollow shaft section and having a sensor device (2) for detecting mechanical stresses affecting the hollow shaft section, the sensor device (2) is arranged in the hollow shaft section, wherein the hollow shaft section has a first radially inwardly protruding formation (12) and a second radially inwardly protruding formation and the sensor device (2) is positively connected with an axial pretension between the first radially inwardly protruding formation (12) and the second radially inwardly protruding formation (20). In a manufacturing process for the production of the machine element, in a first forming step a first radially inwardly protruding formation (12) is produced in the hollow shaft section of the machine element, in a subsequent sensor arrangement step, a sensor device (2) is fitted positively in the hollow shaft section on the first radially inwardly protruding formation (12) and the second radially inwardly projecting formation (20) is produced in the hollow shaft section in a subsequent joining step, by means of which the sensor device (2) is joined positively with an axial pretension between the first radially inwardly protruding formation (12) and the second inwardly protruding formation (20).
A machine element (1, 32) with a one-piece hollow shaft section and with a sensor device (2) for detecting a mechanical stress affecting the hollow shaft section, wherein the sensor device (2) is arranged in the hollow shaft section, characterized in that the hollow shaft section has a first radially inwardly protruding formation (12) and a second radially inwardly protruding formation (20) and in that the sensor device (2) is positively connected with an axial pretension between the first radially inwardly protruding formation (12) and the second radially inwardly protruding formation (20).
