    Abstract: An edge flap arrangement for an aircraft wing includes a main flap element and an actuator for moving the main flap element relative to the aircraft wing. A linkage arrangement supports the main flap element and includes a drop hinge link arrangement having a fixed strut secured to the aircraft wing and a drop link secured to the main flap element. The fixed strut and the drop link are connected by a hinge point having an hourglass bearing assembly having hourglass shaped rollers with a circular cross section symmetrical about a longitudinal axis, first and second axial ends, and an exterior surface. The exterior surface defines a concave engagement surface having a first radius of curvature R1 and a second radius of curvature which is greater than the first radius of curvature R1. The first radius of curvature is between 50 and 95 percent of the second radius of curvature.

    Abstract: An edge flap arrangement for an aircraft wing includes a main flap element and an actuator. A linkage arrangement supports the main flap. The linkage arrangement includes a drop hinge link arrangement. The drop hinge link arrangement includes a fixed strut and a drop link. The fixed strut and the drop link are pivotally connected by a hinge point. The hinge point includes an hourglass bearing. The hourglass bearing includes an inner member, an outer member, and a plurality of hourglass rollers. Any combination of the inner member, the outer member, and the hourglass rollers are fabricated from CREN, Cronidur 30, XD15NW, 422 Stainless Steel, CRES, and/or 440C Stainless Steel. A cage is disposed between the inner member and the outer member. The cage includes a plurality of first rails and a plurality of second rails. Opposing pairs of first rails and second rails define a plurality of pockets.

    Abstract: A seal for a bearing includes an annular retaining ring defining a first radially innermost portion and a first radially outer end; and a resilient ring defining a second radially innermost portion and a second radially outer end. The first radially innermost portion and the second radially innermost portion are aligned with one another and together define a securing root of the seal. The root is adapted to seat in a groove of an inner ring of the bearing. The resilient ring projects radially outward from the annular retaining ring. The resilient ring is more flexible than the annular retaining ring. The second radially outer end defines a sealing surface adapted to slidingly engage an inner bearing surface of an outer ring of the bearing. The first radially outer end of the retaining ring terminates between the first radially innermost portion and the second radially outer end of the resilient ring.
