Abstract: A roller assembly includes an outer ring having an interior having an inner surface extending an overall axial length between first and a second axial ends. The inner surface has a radially inward facing bearing surface extending between first and second radially inwardly extending flanges. The roller assembly includes a one piece inner member extending into the interior and having a groove formed therein between third and a fourth axial ends. A retaining ring is positioned in the groove. A first row of first rollers is positioned in the interior and between the retaining ring and the first radially extending flange. A second row of second rollers is positioned in the interior between the retaining ring and the second radially extending flange. An annular seal engages the inner member and has an overall axial width no more than 6% of the length of the outer ring.

Abstract: A maintenance-free bearing system having self-lubricating features, seals, grooves and slots for use in a cushion hitch assembly for a hitch pull scraper vehicle. An interconnected bearing linkage system having two or more horizontal two-axis combined journal and thrust bearings with self-lubricating liners therein, two or more vertical single-axis sleeve bearings with self-lubricating liners therein and one or more vertical thrust bearing with self-lubricating liners therein, that cooperate with one another to accommodate vertical and horizontal angular movement relative to one another. The vertical thrust bearings incorporate an outer seal assembly and/or an inner seal assembly with a tapered configuration that improves retention of the seal assembly during rotation.

Abstract: A roller assembly includes an outer ring having an interior area defined by an inner surface extending between a first and second axial end thereof. The inner surface has a bearing surface. A flanged headed shaft having an exterior bearing surface extends into the interior area. The shaft has a circumferential retainer receiving surface thereon. Two rows of rollers are positioned in the interior area with a spacer ring therebetween. A retainer ring is secured to the retainer receiving surface. The two rows of rollers and the spacer are axially retained on the shaft by and between the flanged head and the retaining ring so that the roller assembly withstands an axial load of up to 100 percent of an applied radial load.

Abstract: A flexible coupling for attaching a collet to a draw bar includes a draw bar having a first longitudinal axis and a first coupling portion. The first coupling portion includes two or more legs spaced apart from one another with each of the legs having first coupling surface formed thereon. The flexible coupling includes a collet having a second longitudinal axis and a clamping portion proximate one end of the collet. The collet includes a second coupling portion proximate a second end of the collet. The second coupling portion has a second coupling surface formed thereon and configured in a shape complementary to the first coupling surface so that the first coupling surfaces moveably engage the second coupling surface such that the first longitudinal axis and the second longitudinal axis are coaxial when an axial force is applied to the draw bar and the collet.

Abstract: A roller for a mechanical fuel pump assembly includes an elongate body extending from a first axial end to a second axial end of the elongate body over an overall length of the elongate body. The elongate body defines an effective length that is less than the overall length. The elongate body defines a uniform circular cross section over a second length of the elongate body. The second length is 75 to 90 percent of the effective length and the second length extends between a first plane and a second plane. A first area of reduced cross section extends axially outward from the first plane to a third plane located axially inward of the first axial end; and a second area of reduced cross section extends axially outward from the second plane to a fourth plane located axially inward of the second axial end.

Abstract: A ball bearing includes an outer ring having at two outer raceways and an inner ring having two inner raceways. A plurality of balls is disposed in each of the two inner and outer raceways. The plurality of balls include load bearing balls and spacer balls. The spacer balls are disposed between the load bearing balls. Each of the load bearing balls has a single point of contact with each of the two inner and outer raceways. The load bearing balls are preloaded between the outer ring and the inner ring at predetermined force.

Abstract: A guide mechanism, configured for use with a guided attack rocket, includes an inner housing partially disposed in an outer housing. The inner and outer housings each define a forward end and an aft end. A first angular contact bearing is positioned between the outer housing forward end and the inner housing forward end. A second angular contact bearing is positioned between the outer housing aft end and the inner housing aft end. A retaining nut is received over the inner housing forward end. The retaining nut preloads the first and second angular contact bearings. Each of the angular contact bearings includes an inner member disposed within an outer member. The outer member defines an outer raceway and the inner member defines an inner raceway. A plurality of rolling elements is disposed between the outer raceway and the inner raceway.

Abstract: A swaged bearing assembly includes a flange mounted thereon. A bearing inner member has an outer surface at least a portion of which defines an outer engagement surface. A bearing outer member is swaged around the inner member and the inner member is misalignable and rotatable in relation to the outer member. The outer member has an outer surface and an inner surface at least a portion of which defines an inner engagement surface. An area of engagement is defined by an interface of the inner engagement surface of the outer member and the outer engagement surface of the inner member. A flange is mounted on the outer surface of the outer member.
