A bearing assembly for an electrical generator includes a frame, a bearing liner and a ring. The frame is configured to connect with a housing of an electrical generator. The frame includes a frame opening and is made from a first material. The bearing liner connects with the frame. The bearing liner is made from a second material, which is dissimilar from the first material. At least a portion of the bearing liner passes through the frame opening. The ring surrounds the bearing liner. The ring contacts the frame and the bearing liner and maintains a clearance between the portion of the bearing liner passing through the frame opening and the frame.

This assembly includes a ball joint assembled in a casing, and receiving an axle capable of sliding and/or rotating therein. The ball joint is formed from the winding of a fabric of small thickness ranging between 20 μm and 150 μm and mixed with a resin comprising fillers. The fabric has the form of strips having a width ranging between 5 mm and 200 mm; the strips being crossed in several layers.

The composition for a sliding member contains a binder resin, a solid lubricant, and at least one type of resin beads selected from the group consisting of amino resin beads and urethane resin beads. The second coating film layer includes the binder resin and the solid lubricant.

The present invention achieves a high mechanical load capacity of a rod end by means of a component loop that passes around a bearing, where the component may be made of continuous-fiber reinforced composite material with thermoplastic matrix and where the continuous-fiber reinforced composite material with thermoplastic matrix may extend into a threaded stem of the rod end, and the component made of continuous-fiber reinforced composite material with thermoplastic matrix may be enclosed by short-fiber reinforced, long-fiber reinforced, or unreinforced thermoplastic. The threaded stem can be implemented with an external or an internal thread.
