Abstract
A combination bearing is configured to support both axial loads and radial loads. The combination bearing includes a bearing housing including a radial bearing ring and an axial bearing cup. Radial rolling elements are located within the radial bearing ring, are configured to support a radial load, and collectively rotate about a central axis. Axial rolling elements are located within the axial bearing cup, are configured to support an axial load, and are axially offset from the radial rolling elements along the axis. An axial washer directly contacts the axial rolling elements. The axial washer is configured to support the axial load and transfer it toward the axial rolling elements. A sealing washer is disposed about the axis and spaced axially from the axial washer. Oil is retained within the combination bearing during free-wheeling conditions with little to no external oil supply.
