A gas turbine engine including a core engine and a variable pitch fan arranged in flow communication with the core engine is provided. The variable pitch fan includes a plurality of blades coupled to a disk, the blades and disk configured to rotate together about an axial direction of the engine. A rotatable front hub may be provided over a front end of the variable pitch fan, including the disk. The gas turbine engine additionally includes a plurality of trunnion mechanisms coupling each of the plurality of fan blades to the disk. Each trunnion mechanism includes a bearing having one or more components formed of a non-ferrous material, decreasing a weight of the respective trunnion mechanism and allowing for, e.g., a smaller front hub.
