摘要： An axial bearing assembly is provided having a first washer forming a first raceway and including a radially inner retention flange, and a second washer forming a second raceway axially spaced apart from the first raceway, with the second washer including a radially outer retention flange. A cage including a radially inner rim, a radially outer rim, and a plurality of segments extending between the radially inner and outer rims defining a plurality of rolling element pockets is located between the first and second raceways. Rolling elements are located in at least some of the pockets. The radially outer rim of the cage includes a circumferentially extending groove on a radially outer surface. Outer retention tabs extend from the radially outer retention flange into the circumferentially extending groove.

摘要： A bearing module that supports adjacent ends of coaxial shafts, includes an outer ring having first and second axially adjacent raceways and first and second flanges located at the respective ends. A first group of rolling elements rolls on the first raceway, and a second group of rolling elements rolls on the second raceway. A first cage retains the first group of rolling elements circumferentially spaced apart from one another, and a second cage retains the second group of rolling elements. An axial bearing is retained axially between the first and second groups of rolling elements, and has axial bearing rolling elements that are configured for rolling contact with (a) facing axial side raceways on first and second inner rings supported respectively on the first and second groups of rolling elements, (b) the adjacent ends of the two coaxial shafts, or (c) integral washers of the axial bearing.

摘要： A tapered roller bearing includes an inner ring, an outer ring, a plurality of tapered rollers, and an annular cage that holds the tapered rollers. The cage has a small annular portion positioned on one side, in the axial direction, of the tapered rollers, a large annular portion positioned on the other side, in the axial direction, of the tapered rollers, and a plurality of cage bars that couple the small annular portion and the large annular portion to each other. The cage bars each have a cage bar end portion that is positioned between the large annular portion and a large rib and that projects toward the other side in the axial direction with respect to large end surfaces of the tapered rollers.

摘要： A radial support bearing having a cylindrical cage including a central portion, a first end portion and a second end portion, the central portion defining a plurality of roller pockets, and at least one projection extending radially inwardly from an inner surface of the cage, a plurality of rollers, each roller being disposed in a respective roller pocket, a cylindrical outer sleeve disposed about an outer surface of the cage so that the inner surface of the outer sleeve is adjacent the plurality of rollers, and an o-ring adapted to be axially fixed relative to the shaft. The o-ring is slidably received between the at least one projection of the cage and the central portion of the cage so that the cage is axially fixed with respect to the shaft.

摘要： The present invention provides a tapered roller bearing used in a planetary gear speed reducer, and including an outer race, and a retainer formed with a first annular portion, a second annular portion, and pillars. At least one retainer guiding surface (raceway) which guides the retainer in the radial direction is formed only on the inner periphery of the outer race. Guided surfaces are formed at least either on the pillars or on the first and second annular portions, and guided by the at least one retainer guiding surface. Therefore, it is possible to guide the axial central portion or both side portions of the retainer, to make the retainer less likely to tilt due to a centrifugal force, and to apply a preload to both side surfaces of the outer race.

摘要： A tapered roller bearing includes an inner ring, an outer ring, a plurality of tapered rollers provided in an annular space formed between the inner and outer rings and rolling on an inner raceway surface and an outer raceway surface, and an annular cage that holds the tapered rollers. The cage has a small annular portion positioned toward an axially first side with respect to the tapered rollers, a large annular portion positioned toward an axially second side with respect to the tapered rollers, and a plurality of cage bars that couples the small annular portion and the large annular portion together. A minute clearance is formed between the inner ring and the large annular portion and between the outer ring and the large annular portion, respectively.

摘要： A thrust bearing includes: a retainer that is provided with a plurality of pockets; a plurality of rollers that are arranged so as to freely rotate inside the plurality of pockets; and at least one first race that has an annular-shaped first race section in which the plurality of rollers move. The first race is provided with a hook curl section that is formed by bending the first race section from an outer-diameter-side periphery thereof toward the inner-diameter side obliquely in the radial direction, and an outer peripheral surface of the retainer has a conical surface that is formed so as to be substantially parallel to an inner peripheral surface of the hook curl section. The inner peripheral surface of the hook curl section holds the retainer without separating therefrom by contacting the outer peripheral surface of the retainer in a sliding manner.

摘要： A rolling bearing includes an inner ring, an outer ring, a plurality of rolling elements disposed between the inner ring and the outer ring, and a plurality of cage segments separating circumferentially adjacent ones of the plurality of rolling elements. Each of the cage segments has an axial bridge portion and side plates at axially opposite ends of the bridge portion, each of the side plates having a convex end and a concave end circumferentially spaced from the convex end. The convex end of a first one of the side plates contacts the concave end of a second one of the side plates.
