Claim:
1. A self-aligning instrumented bearing comprising: an outer ring, an inner ring delimiting a rolling chamber having at least one row of rolling elements disposed therein; and a detection device including a sensor integral with the outer ring and a target integral with the inner ring configured to detect a relative rotation between the outer ring and the inner ring around a central axis; wherein the outer ring has an inner surface in the form of a first spherical portion centered about a tilting center of the bearing and having a first radius with respect to the tilting center, the inner surface of the outer ring forming a rolling surface for the rolling elements; and wherein the sensor having a sensor inner surface in the form of a second spherical portion centered on the tilting center and having a second radius with respect to the tilting center, the target having a target outer surface in the form of a third spherical portion centered on the tilting center and having a third radius with respect to the tilting center, wherein the first radius of the inner surface of the outer ring is greater than the second radius of the sensor inner surface, and, the second radius of the sensor inner surface is greater than the third radius of the target outer surface such that the first radius of the inner surface of the outer ring is greater than a distance between the tilting center of the bearing and a specific position of the target that is farthest from the tilting center.
