    摘要： When an inner-diameter-side opening of each of a plurality of radial holes (15) in an outer race (12) is projected onto an outer circumferential surface of a retainer (14) along an extension line of the center line (XI, X2) of the radial hole (15a, 15b), at least a portion of the inner-diameter-side opening of the radial hole is located, in the axial direction, within a region between two circles each formed by connecting axial-direction ends of adjacent pockets in the retainer (14). When the center line (X1) of one of the radial holes (15a) matches the phase, in the circumferential direction, of the center (O) of a ball (13), a projection of the inner-diameter-side opening (30) of one of the other radial holes (15b), when the inner-diameter-side opening thereof is projected as described above, is separated from the ball (13) and the inner circumferential surface of the pocket (P) as viewed from the radial direction of the ball bearing (10), and the center line of said one of the other radial holes overlaps said pocket as viewed from the axial direction of the ball bearing.

    摘要： A sealing assembly (1), including an annular metal insert (6) and an annular seal (7) made of elastomeric material, integrally constrained in one piece to the metal insert having: one elastically deformable first annular lip (8), which radially extends in catilever manner from a first annular edge (9) of the metal insert and being substantially C-shaped in radial section; and an annular coupling portion (10) arranged on a second annular edge (11) of the metal insert, opposite to the first, and provided with an elastically deformable second (15), third (16) and fourth (17) annular lip, which extend in cantilever manner from the coupling portion; wherein the second and the third lip (15, 16) are opposite and adapted to assume a deformed configuration, in use, in which they are substantially aligned along an oblique straight line; and the metal insert being circumferentially pfovided with a plurality of indentation (19), each having a radial depth substantially equal to the radial extension of the coupling portion, so that the second annular edge extends in an alternating manner, inside and substatially outside the coupling portion.

    摘要： The invention relates to a radial bearing (15) having a cassette seal (20), and to the cassette seal (20) itself, in which the radial bearing has an inner ring (26), an outer ring (3), and rolling bodies (4) which are arranged between them, and in which the cassette seal (20) is arranged in a press fit (27a, b) axially next to the rolling bodies (4) between the inner ring (26) and the outer ring (3), wherein the cassette seal (20) has a carrier, a seal which is fastened to it and a bent sheet-metal ring, against which sealing lips of the seal bear. For the inexpensive manufacture and the effective sealing of a radial bearing (15) of this type, there is provision according to the invention for an additional sealing means (32) to the static seal to be arranged between the bent sheet-metal ring and the bearing ring (26).
