More Information
Summary:A screw device is provided which can detect damage to a groove of a screw shaft, the damage being hidden by a nut, with a high probability. At least two circulation components are mounted on a nut in such a manner as to form at least two circulation circuits that circulate rolling elements. The nut is provided with a sensor that detects a displacement of a groove of a screw shaft between the adjacent circulation circuits.
