摘要： A spacer includes opposite first and second portions facing one another, and at least two spaced reinforcing beams connected to the first and second portions and extending transversally with respect to the portions, the reinforcing beams being disposed both on one side of the first and second portions. The spacer further includes at least one abutting beam connected to the first and second portions, extending transversally with respect to the portions and located on the side opposite to the reinforcing beams. The first and second portions delimit together with the reinforcing and abutting beams a pocket configured to receive at least a contact roller.

摘要： A tapered roller bearing includes an inner ring, an outer ring, a plurality of tapered rollers, and an annular cage. The cage has a small annular portion, a large annular portion, and a plurality of cage bars that couples the small annular portion and the large annular portion together. The cage is enabled to come into contact with an inner peripheral surface of the outer ring at least on an axially first side so that the contact allows the cage to be positioned in a radial direction. Each of the cage bars has pocket surfaces each of which faces an outer peripheral surface of the corresponding tapered roller, and each pocket surface has a flat surface shape that is straight in a direction from the inner ring toward the outer ring and that is enabled to come into line contact with the corresponding tapered roller.

摘要： A bearing cage for a roller bearing assembly includes an annular body defining a circumferential centerline extending therethrough. The annular body includes an outer circumferential surface, an opposing inner circumferential surface, and a plurality of circumferentially spaced roller cavities defined therein. Each roller cavity of the plurality of roller cavities is configured to receive an associated roller element. Each roller cavity includes a first radial cross-wall defined within the annular body extending from the outer circumferential surface to the inner circumferential surface. Each roller cavity further includes an opposing second radial cross-wall defined within the annular body extending from the outer circumferential surface to the inner circumferential surface. At least a portion of the first radial cross-wall and at least a portion of the second radial cross-wall are complimentary to the associated roller element.

摘要： In a tapered roller bearing, a large rib is provided at one end of an inner ring in the axial direction, and projects radially outward. A lubricating oil holding member is integrated with an outer ring, and disposed at a position overlapping the large rib in the radial direction. The lubricating oil holding member includes a tubular portion and an annular portion. An inclined surface is disposed on the outer peripheral surface of the large rib at one end in the axial direction. The distance from the rotational axis of the inner ring to the inclined surface becomes larger from one side in the axial direction toward the other side. An end of the inclined surface is positioned, in the axial direction, between the annular portion and one end of the outer ring in the axial direction.

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.
