Abstract
A bearing is mounted in a bearing housing which contains lubricating oil. The bearing includes radially spaced outer and inner rings which confine bearing rollers therebetween. A radially outer surface of the outer ring contains a circular groove in which a strip of lubricant-conducting material is situated. A lower portion of the strip communicates with lubricant, whereby the strip conducts lubricant upwardly by capillary action to a radial passage formed through the outer ring at an upper location thereof. The lubricant gravitates through that passage to the space in which the bearing rollers are disposed. The radially outward facing side of the groove is closed-off by an inner surface of the housing to confine the lubricant within the groove.
