ABSTRACT:
A cargo deck bearing assembly (8) comprising a housing (10) formed of a lightweight material, and means (14) integral therewith for attaching the housing (10) to an airplane cargo deck. A plurality of cavities (18) are provided in the housing (10) at its upper surface (20), generally arranged in the form of a circle. A generally hemispherical cup (22) is disposed in each of the cavities (18). A plurality of small bearing balls (24) are disposed in a single layer over the inner surface of the cup (22), and a single larger bearing ball (28) is disposed over the layer of small bearing balls (24). A rigid skid plate (30) is affixed to the upper surface (20) of the housing over the bearing balls. The skid plate (30) is provided with a plurality of circular apertures (34), one aperture superposed over each of the larger bearing balls (28). The structure results in a lightweight cargo bearing assembly (8) providing low resistance to movement of cargo bins thereover in any direction.
