Abstract: A loader slot bearing includes an annular housing having first and second axial surfaces and an interior area extending therebetween. The interior area has a first inner surface that extends between the first and second axial surfaces. A portion of the inner surface is a first bearing surface that has a spherical contour. A slot extends partially into the first inner surface from the first axial surface. The slot has a first width. The annular housing is manufactured from a precipitation hardened corrosion resistant stainless steel. The loader slot bearing includes a truncated ball that is positioned in the slot and rotated so that the truncated ball is rotatably retained by the first bearing surface. The truncated ball is angularly misalignable relative to the housing and is manufactured from a 440C stainless steel. A dry lubricant is applied to the spherical exterior surface of the truncated ball.

Abstract: A tapered roller bearing assembly includes a one-piece inner ring that has two outer raceways oriented at angles relative to a longitudinal axis and a first outer ring with a first inner raceway and a second outer ring having a second inner raceway. The bearing assembly includes a spacer ring that has an axial width and is positioned around the inner ring and between the first and outer rings. A plurality of rolling elements is in rolling engagement with the first outer raceway and the first inner raceway. A plurality of rolling elements is in rolling engagement with the second outer raceway and the second inner raceway. The axial width is selectively established to obtain a predetermined axial clearance between the inner ring and the first outer ring and the second outer ring.

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 cam follower assembly includes a ball bearing having an outer ring and an inner assembly which includes two or more segments. The inner assembly is disposed in the outer ring with a full complement of balls disposed therebetween. The outer ring and inner assembly each include a race having a gothic arch cross sectional configuration that causes the balls to roll on two portions of each race.

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.
