A bearing providing a first ring, a second ring and at least one row of rolling elements radially located between raceways disposed on the first and second ring, a single optical sensing fiber mounted in a groove provided on a surface of the first ring radially opposite to the raceway of the first ring, the fiber having at least a sensing part. The groove including a first branch extending from a first frontal surface of the first ring and being at least partially incurved along at least one radius of curvature to extend towards a circumferential groove parallel to the first frontal surface; a second branch extending from a second frontal radial surface of the first ring, axially opposite to the first frontal surface, connected to the first branch, the second branch being at least partially incurved along at least one radius of curvature.

A method and device for effecting automatic centering of an annular workpiece on a rotating surface having a rotational center involves arbitrarily positioning the workpiece on the slowly rotating surface, applying a support for the workpiece by way of spaced apart contact members that individually contact the workpiece and are synchronously movable in a guided reciprocating manner towards and away from the rotational center of the rotating surface. The contact members are gradually retracted away from the rotational center of the rotating surface until the workpiece is unaffected by the contact members during one revolution of the rotating surface so that the workpiece is centered, and the center of the workpiece coincides with the rotational center of the rotating surface. At least one of the contact members is provided with a mechanism for counteracting a friction force acting on the workpiece.
