    摘要: An injection molding tool for producing a cage for a linear bearing in which several rolling elements are positioned in the cage in the direction of its longitudinal extent in the assembled state includes two tool halves each provided with protrusions. The protrusions extend into the cavity of the tool during the injection molding process and form a portion of a receiver pocket for receiving a rolling element. To make the injection molding process simple and economical, the protrusions are fixedly connected with the tool halves, with the protrusions being are shaped in such a way that, when acting together, they form holding elements for retaining the rolling elements in the receiver pockets in the cage when the injection molding tool is closed. The holding elements are thus integrated into the basic geometry of the cage. A rolling bearing cage for a linear bearing is provided with a plurality of receiver pockets for holding rolling elements next to each other in a manner arranged along the longitudinal extent of the bearing. The cage is also provided with holding elements integrated into the basic geometry of the cage for retaining the rolling elements within the receiving pockets.

    摘要: A bearing unit includes a housing provided with a cylindrical bore and a linear bearing positioned within the cylindrical bore. The linear bearing includes a cage in which are arranged a plurality of endless ball rows each defined by a longitudinally extending ball track for load-bearing balls, a longitudinally extending return track for non-load-bearing balls, and deflection tracks connecting ends of the longitudinally extending ball track and the longitudinally extending return track. Each longitudinally extending ball track opens radially outwardly with a track plate being arranged to cover the longitudinally extending ball track for the load-bearing balls. The cylindrical bore of the housing is provided with a plurality of recesses each located in an area of the cylindrical bore facing one axial end of one of the track plates to permit radial deflection of the one axial end of the track plate.

    摘要: A radial seal useful in linear ball bearings and designed to be secured during transportation as well as during operation of the bearing includes an arcuate disk portion having opposite sides. An arcuate projection is provided on each side of the disk portion, at least one of which is axially oriented. The projections are designed to have different diameters. This produces a stepped seating surface along the outside diameter of the radial seal that effects a reliable seating of the radial seal in the linear ball bearing. The radial seal can also be designed with two axially oriented projections disposed at different diameters on one side of the disk portion for projecting into an annular groove on the frontal face of the outer ring of the linear ball bearing. By constructing the projections with circumferential outer faces that slightly diverge in a cone-shaped manner, the projections further inhibit the seal from falling out of the groove.

    摘要: A ball bearing for permitting longitudinal movements with respect to a shaft includes a cage provided with at least two longitudinally extending guide tracks having opposite ends that are connected by semicircular turn around tracks. A plurality of balls are positioned in the guide tracks, with balls positioned in one of the guide tracks forming load-bearing balls and balls positioned in another one of the guide tracks forming non-load-bearing balls. The longitudinally extending guide track for the load-bearing balls is provided with a slit that is open radially inwardly for passage of the balls in a direction radially inwardly towards the shaft. The longitudinally extending guide track for the non-load-bearing balls has an interior wall which, in cross-section, possesses at least two substantially diametrically opposed first sections having a circular contour and at least two substantially diametrically opposed second sections laterally offset from the first sections and having a base that is set back from the circular contour.
