摘要： An ultrathin walled rolling bearing in which the noise level is reduced and thus the sound characteristics are improved is provided. The rolling bearing is composed of an outer member having in its inner periphery a raceway surface, an inner member having in its outer periphery a raceway surface, a plurality of rolling elements interposed between the raceway surfaces of the outer and inner members, and a cage for circumferentially equi-spacing the rolling elements. In this bearing, the ratio of the diameter DB of the rolling element to the pitch circle diameter PCD of the bearing is equal to or less than 0.03. In addition, the ratio L/M falls within a range of 0.8 to 0.95 in which L is the radial thickness of the cage and M is the radius difference between the inner peripheral surface of the outer member and the outer peripheral surface of the inner member.

摘要： A tapered roller bearing and an automotive gear shaft support device can ensure a long endurance life even in the state in which debris is mixed. On the surfaces of an outer ring, inner ring, and tapered rollers formed from carburized bearing steel having an oxygen content of 9 ppm or less, carbo-nitrided layers having a carbon content of 0.80 wt % or over, a Rockwell hardness HRC of 58 or over, and a residual austenite content of 25-35 vol % are formed to increase mechanical properties and fatigue characteristics of the parts and to stably maintain the carbo-nitrided layers on the surfaces of the parts to a quality having suitable toughness, thereby markedly improving the endurance life of the tapered roller bearing in a state in which debris is mixed.

摘要： Reciprocating or push-pull control cable assemblies have fittings permanently attached, preferable by swaging or other mechanical deformation process, to the ends of a control cable or core that reciprocates within an outer casing. The fittings have a projected width no greater than the inner diameter of the casing. As a result, the entire control cable, with fittings attached, can be pulled through the casing to remove the control cable for inspection, maintenance or replacement. The cable also have a unique combination of ball joint assemblies and excluder seals that effectively exclude contaminants from the interior of the casing.

摘要： 1,068,767. Bearings. S. MESSERSCHMIDT. Feb. 9, 1966 [March 13, 1965], No. 5733/66. Heading F2A. In a convex-roller bearing the rollers have a radius of curvature in a plane containing the bearing axis which is at least twice the bearing radius, i.e. the distance between the bearing axis and the mid-point of a roller axis. Each roller has equal areas of contact (18, 19, Figs. 3 and 4, not shown) with the outer and inner races. In Fig. 1 (not shown) the outer race has a cylindrical raceway, and the inner race has a curved raceway whose curvature in said plane is equal to that of the roller. Circumferential projections (16) on the inner race guide the rollers. Alternatively a curved inner raceway (17) extends beyond the ends of the rollers. Conical, needle and thrust bearings are shown in Figs. 5-9 (not shown).

The metering piston includes a first metering chamber and a second metering chamber that are each connected to the at least one lubricant outlet. The lubricant injector further includes first and second lubricant channels, and in a first switching state of the control piston the lubricant inlet is connected via the first control space to the first lubricant channel and the second metering chamber, and in a second switching state the lubricant inlet is connected via the second control space to the second lubricant channel and the first metering chamber.

摘要： A bicycle bearing system comprising: an integrated cup, the integrated cup having an outer diameter; a plurality of rolling elements configured to abut and rotate against a first race groove located on an inner surface of the integrated cup; a second race groove configured to abut and rotate about the plurality of rolling elements, the second race groove located on an inner surface of the inner race, the inner race having an inner diameter; where the rolling elements do not have a separate outer race, but rather the inner surface of the integrated cup acts as the outer race to the rolling elements; and where the rolling elements, integrated cup and inner race are axially locked when assembled as a single cartridge unit due to the geometry of the rolling elements, first race groove and second race groove.

摘要： A tapered roller bearing includes an inner ring with a large rib, an outer ring, and multiple tapered rollers. Each of the tapered rollers has, at its axial end, a large end face that is a convex surface. The large rib has a rib face that is a concave surface and that is in contact with the large end face. When a distance from a position of contact between the large end face and the rib face to a cone center of the corresponding tapered roller is defined as R, a curvature radius of the large end face is defined as Rr, and a curvature radius of the rib face is defined as Ri, an inequality represented by 2≤(Ri −R)/(R−Rr)≤10 is satisfied, where Rr
