Abstract:
1. A bearing comprising: a fixed outer ring forming a lubrication ring having at least one lubrication duct extending between an outer surface and an inner surface of the outer ring, a rotatable inner ring, and wherein the at least one lubrication duct of the lubrication ring is placed so that the scalar product of: a vector collinear to a longitudinal axis of the lubrication duct, and a vector collinear to a tangent line to an outer cylindrical surface of the inner ring, at the point where the longitudinal axis of the lubrication duct intersects the outer cylindrical surface of the inner ring, and oriented in the same direction as a rotation direction of the inner ring, is greater than zero, and wherein the vectors are projected in a plane perpendicular to a rotation axis of the bearing.
