Abstract
This bearing comprises a fixed outer ring and a rotatable inner ring, and at least one lubrication ring having at least one lubrication duct extending between an outer surface and an inner surface of the lubrication ring. The at least one lubrication duct is placed so that the scalar product of a vector collinear to the longitudinal axis of the lubrication duct, and a vector (VL1) collinear to the tangent line (L1) to an outer cylindrical surface of the inner ring, at the point where the longitudinal axis of the lubrication duct (270) intersects the outer cylindrical surface of the inner ring, and oriented in the same direction as the rotation direction (F) of the inner ring, is strictly superior to zero, said vectors being projected in a plane (P2) perpendicular to the rotation axis of the bearing.
