A cage for a double row roller bearing assembly is disclosed. The cage includes an annular rim and two pluralities of webs. A first plurality of roller pockets are defined between adjacent ones of a first plurality of webs. Each of the webs of the first plurality of webs includes two first prongs and a first slot defined between the two first prongs. A first partial cylindrical guide surface is arranged on each first lateral surface of the first plurality of webs, and a first undercut is defined between each of the first lateral surfaces and the annular rim. Two adjacent ones of the first prongs are elastically deformable away from one another for insertion of a roller. A second plurality of webs are also provided with the same features as the first plurality of webs.

A spherical roller bearing having a specific pitch circle diameter (PCD) that includes an outer ring, an inner ring, a plurality of roller elements arranged in first and second roller rows, each roller element providing an axially inner end, and a cage for guiding the roller elements in the first and second roller row, the cage having a plurality of cage pockets. One of the roller elements disposed within each cage pocket. Each respective cage pocket has a bottom that faces the axially inner end of the roller element in each cage pocket. A radially inner end of the cage pocket bottom contacts the axially inner end of the roller element only at a location radially equal to the specific PCD, the cage pocket bottom angled such that the cage pocket bottom abuts the axially inner end of the roller element at an angle such the contact is not flush.

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.
