Abstract: An expandable sleeve for an interference fastener has a hollow elongate stem extending axially between an insertion end and a head portion. The elongate stem has an inside surface and an outside surface. A portion of the stem has a fluted shape and/or has a cylindrical shape with a conical portion.

Abstract: A bearing includes an outer ring with a first outer roller race, a second outer roller race, and a radially inward facing outer ball race. The bearing includes a first and second inner rings that axially abutting one another at an abutment interface. The first inner ring has a first inner roller race, the second inner ring has a second inner roller race that are disposed in an interior area coaxially with the outer ring. A plurality of first rollers rollingly engage the first outer roller race and the first inner roller race. A plurality of second rollers rollingly engage the second outer roller race and the second inner roller race. A plurality of balls rollingly engage the outer ball race and the inner ball race.

Abstract: A bolt for an interference fastener and a fastener system is provided. The bolt has a body extending axially between a first end and a second end. The body has a threaded area extending axially inward from the second end and a head configured on the first end. A cylindrical expansion area extends axially between the head and the transition area. The transition area is disposed axially between the cylindrical expansion area and the threaded area.

Abstract: A rolling element bearing includes an outer member having an outer member interior surface and an outer member exterior surface. The bearing includes an inner member having an inner member interior surface and an inner member exterior surface and a plurality of rolling elements disposed between the inner member and the outer member. The bearing includes a plurality of random-length slug separators. The separators are of a first length, a second length or a third length, which are not equal. One of the plurality of random-length slug separators is disposed adjacent to at least one of the plurality of rolling elements. The plurality of rolling elements are non-rhythmically spaced apart.

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.
