摘要： A bearing assembly suitable for use in a motorcycle steering assembly includes an inner ring member having a convex inner race surface with opposing axial edges. An outer ring member encircles the inner ring member and defines a raceway space therebetween. The outer ring member includes at least two axially spaced outer race surfaces defining a lubrication groove therebetween. Flanges axially outwardly spaced from each outer race surface extend radially inwardly past the outer race surfaces to capture a roller therebetween. A plurality of rollers are disposed in the raceway space between the flanges. Each of the rollers include a concave radial race surface interposed between axially spaced radial race surfaces. Each of the axially spaced radial race surfaces engage one of the axially spaced outer race surfaces of the outer ring member and the concave radial race surface engages the inner ring member convex inner surface. In one embodiment, a seal spaced axially outwardly from each axial end of the rollers and disposed between the inner and outer ring members seal the rollers between said inner and outer ring members, and a collar is fixed to each axial end of the inner ring member to unitize the bearing assembly.

摘要： A drill bit for use in a borehole at least partially containing drilling fluid includes a bit body having at least two bit components, including at least one leg, the leg having a journal segment, and a roller cone rotatably mounted upon the journal segment and forming at least one bearing cavity therebetween. Also included is an annular primary seal disposed between the leg and the roller cone, an annular secondary seal disposed between the leg and the roller cone and between the annular primary seal and the borehole and an annular space disposed between the annular primary seal and the annular secondary seal, the annular space at least partially containing fluid and being in substantially absolute fluid isolation from the bearing cavity and a conduit for permitting the flow of fluid from the annular space to the borehole. The annular secondary seal may be primarily elastomeric and a passage for permitting the flow of fluid may further permit the flow of fluid from the borehole to the annular space. The annular space may at least partially include a grease possessing a water washout value of under approximately 50% per ASTM D-4049 water spray test for lubrication characteristics and the grease may include a polymer tackifier of between approximately 1% and approximately 5% by weight.

摘要： A bearing assembly having coaxial inner and outer bearing races, a plurality of rolling elements which ride in respective raceways in the inner and outer races, and annular sealing elements interposed between the inner and outer races for defining annular lubricant containing chambers on opposed axial sides of the rolling elements. For facilitating circulation of lubricant between moving parts during use of the bearing, the outer bearing race is formed with lands which extend axially outwardly of the raceway with a slight radially inwardly directed taper relative to the bearing axis. In some embodiments, the tapered lands are formed with a convexly curved contour.

摘要： A bearing assembly having coaxial inner and outer bearing races, a plurality of rolling elements which ride in respective raceways in the inner and outer races, and annular sealing discs interposed between the inner and outer races for defining annular lubricant containing chambers on opposed axial sides of the rolling elements. For facilitating circulation of lubricant between moving parts during use of the bearing, the outer bearing race is formed with lands which extend axially outwardly of the raceway with a slight radially inwardly directed taper of about 10.degree. to the bearing axis.

摘要： A method of inserting an H-Seal in a bearing, the H-Seal having two ends, two upper lips, two lower lips and a vertical flange positioned between the bearing that secures the upper and lower lips together, the bearing having seal faces, inner and outer rings and a gap therebetween. The method provides including an insertion tool assembly, priming the H-Seal into the insertion tool, sliding the tool with the H-Seal loaded therein within a slot, placing the lower lips back on their respective face, allowing the lower lips to recover their initial shape. The tool moves the lower lips to a vertical position (T shape), inserts the seal between the rings and the lower lips recover their initial shape and places them naturally back on their respective faces.
