Abstract: An electrical conductor for a bearing includes an electrically conductive spring ring having a split therein. The spring ring has a plurality of first electrical contact surfaces in electrical communication with a plurality of second electrical contact surfaces. The plurality of second electrical contact surfaces are positioned radially outward from the plurality of first electrical contact surfaces. The plurality of first electrical contact surfaces and the plurality of second electrical contact surfaces are movable relative to one another.

Abstract: An actuation system for deploying and retracting a lift assisting device of a wing of an aircraft, is presented. The actuation system includes a track pivotally coupled to the lift assisting device, a shaft rotating in response to flight control signals to deploy or retract the lift assisting device, means for actuating the lift assisting device between a retracted position and a deployed position along an arcuate path, a plurality of track roller bearings and a plurality of side roller bearings. The roller bearings rotatably contact the track to guide the track along the arcuate path. The track roller bearings are comprised of an outer ring, a split inner ring and liners disposed between bearing surfaces of the outer and the inner rings. The split inner ring is configured for accommodating deflection and bending of a mounting pin coupling the track roller bearing in proximity to the track.

Abstract: A compressor assembly comprising a housing having a shaft bore therein, a main shaft positioned for rotation within the shaft bore, at least one roller thrust bearing and a thurst surface bearing clip. The thrust surface bearing clip comprises a first position configured for fixed engagement with the housing and a second portion extending from the first portion and configured for supporting a thurst surface in a position spaced from the rotating shaft, the thrust surface providing a bearing surface for the roller thrust bearing.

Abstract: A rocker arm assembly for a fixed rocker shaft has an open rocker arm body containing a bearing supported radially by the rocker arm body bottom wall. The rocker arm side walls axially position the bearing.

Abstract: The rocker arm bearing assembly has a rocker arm which oscillates on a bearing support member and an associated pair of bearings. The bearings are self-contained units with an outer race, an inner race, and multiple rollers positioned between the two races. Full-complement radial bearings are preferably utilized. The bearings are supported on the bearing support member to form an integral unit which can be dropped into the rocker arm. This allows for speedy assembly of the rocker arm with the bearing and support member unit.

Abstract: The oscillating bearing has an arcuate inner raceway, an arcuate outer raceway, and an arcuate retainer between the raceways. The raceways and retainer have aligned openings for receiving a stud. On each side of the retainer opening the retainer has a pair of arcuate roller pockets extending in the oscillating direction and longitudinally spaced from the retainer opening. A roller is located in each roller pocket.
