The lubrication area comprises one or more oil inlets operatively connected to an oil supply, and one or more oil outlets. The vertical distance between the outlet(s) and the lowest point of the lubrication area is 0-0.2 times the inner diameter of the outer bearing race. The inlet (s) and the oil supply are configured to supply an oil flow not exceeding the drain capacity of the one or more outlets.
