    • A bearing assembly includes a first race with an axially extending section and a radially extending section, a second race with an axially extending section and a radially extending section, a cage supported between the first and second races, and a plurality of rolling elements circumferentially spaced within openings formed in the cage. A radial lubrication passage with an inlet and an outlet extends through at least a portion of the cage. The radially extending section of the first race and the axially extending section of the second race define a first annular gap. The radially extending section of the second race and the axially extending section of the first race define a second annular gap. Preferably, the inlet is in fluid communication with the first annular gap and the outlet extends axially through the cage and is aligned with the second annular gap.
    • 轴承组件包括具有轴向延伸部分和径向延伸部分的第一座圈,具有轴向延伸部分和径向延伸部分的第二座圈,支撑在第一和第二座圈之间的保持架以及周向间隔开的多个滚动元件 在笼中形成的开口内。 具有入口和出口的径向润滑通道延伸穿过保持架的至少一部分。 第一座圈的径向延伸部分和第二座圈的轴向延伸部分限定第一环形间隙。 第二座圈的径向延伸部分和第一座圈的轴向延伸部分限定第二环形间隙。 优选地,入口与第一环形间隙流体连通,并且出口轴向延伸穿过保持架并与第二环形间隙对准。
