Systems and methods are presented for directing oil to a bearing of a rotatable shaft. A system comprises a bearing race, a nozzle, and an oil catcher. The bearing race defines a first radial passage and a second radial passage axially displaced from the first radial passage. The nozzle is arranged to eject a stream of oil under pressure toward the shaft. The oil catcher is positioned between the bearing race and the shaft. The oil catcher comprises an annular catching flange at least partly defining a catchment region. The oil catcher defines a first channel extending from the catchment region to the first radial passage of the bearing race and a second channel extending from the catchment region to the second radial passage of the bearing race.
