  • Patent number: 5161896
    Abstract: In a rolling bearing for linear movements, two rolling member circuits arranged between one arm of a U-shaped guide carriage and a lateral face of a guide rail, are substantially perpendicular to one another with their force transmission planes and are substantially parallel to one another with their circuit planes. All rollers have parallel axes in each of the two roller circuits. The load-transmitting row of rollers and the return row of rollers are offset from one another in the axial direction of the rollers in both roller circuits.

  • Patent number: 5044779
    Abstract: In a linear ball bush of part-annular form it is proposed that part-annular seals are secured against rotation about the cage axis by shape-locking engagement with a cage and are movable radially in relation to the cage axis over their substantially entire circumferential extent. Further it is proposed that longitudinal seal strips each comprise a root part received by a longitudinal groove of the cage and a tongue part resting on the shaft, these longitudinal sealing strips being provided with projections at their ends which rest under a longitudinal tension against an axially directed support shoulder of the cage.

  • Patent number: 4989996
    Abstract: A linear ball bush, wherein at least one straight ball row of a ball circuit bears radially outwardly against a running plate, which is inserted in an associated aperture of a cage and possesses an outer face for bearing against an inner circumferential surface of a bearing housing bore seating the cage, is filled in the manner that the balls, with the running plate tilted at one end out of the aperture, are introduced via a filling slope at the open end of the aperture and/or a filling chamfer at the outwardly tilted end of the running plate into a straight portion of a track, and that after the balls of the ball circuit have been completed, the running plate is tilted back into an operating position and is secured in the operating position.
