    material distribution groove can be supplied with lubricating oil.
    Furthermore, it can be provided that the sliding surface is formed on an outer lateral surface of the sliding bearing, the lubricant distribution groove being formed by a recess in the form of a flat. Such a plain bearing is
    easy to manufacture and also has good sliding properties.
    In addition, it can be provided that the joint has an exemption over the entire axial extent of the slide bearing and that an axial extent of the lubricant distribution groove extends only over a partial section of the axial extent of the slide bearing. Through these measures it can be achieved that the lubricant distribution groove is central with respect to the axial extent of the plain bearing and thus the lubricating oil can be collected in the lubricant distribution groove.

The process has the following process steps:
    - Providing a support body strip with a first longitudinal end and a second longitudinal end;
    - Rolling the support body strip to a socket which forms the support body; - Integrally connecting the first longitudinal end and the second longitudinal end of the support body strip at a joint;
    - Introducing the lubricant distribution groove into the sliding layer, the lubricant distribution groove being arranged at a point on the slide bearing at which the
    Joining point is formed.
    The process according to the invention has the surprising advantage that the process steps according to the invention make it particularly advantageous

    The support body 27 is preferably made of a metallic material, usually steel, but can also consist of a material with which the same or a similar function, namely the provision of the mechanical strength of the plain bearing 22, can be realized. For example, a wide variety of copper alloys, such as Brass, bronzes, use fin-
    the.
    The bearing metal layer 28 is formed by a bearing metal alloy. Bearing metal alloys of this type are known from the prior art. For example, the bearing metal alloy can be made from an alloy based on tin, bismuth, indium, lead or aluminum, as well as alloys, possibly containing high lead
    ger, CuPb or AlSn or AlBi-based.
    Although the slide bearing 22 is shown as a three-layer bearing element in FIG. 1, the slide bearing 22 can also have fewer or more than three layers. For example, the polymer layer 29 can be applied directly to the support body 27. Common intermediate layers, e.g. at least one binding layer or at least one diffusion barrier layer, if necessary. This at least one binding layer can be arranged between the support body 27 and the bearing metal layer 28 and / or between the bearing metal layer 28 and the polymer layer 29. This at least one diffusion barrier layer can be between the support body 27 and the bearing metal layer 28 and / or between the
    Bearing metal layer 28 and the polymer layer 29 may be arranged.

As can be seen from FIG. 5, it can be provided that a support body strip 32 is provided which has a first longitudinal end 33 and a second longitudinal end 34. In a first exemplary embodiment, the support body strip 32 can already have the sliding layer 30 applied to the support body strip 32. The sliding layer 30 can for example
    be applied to the support body strip 32 by roll cladding.
    In a further embodiment variant it can also be provided that the sliding
    layer 30 is first applied to the finished rolled support body 27.
    As can be seen from FIG. 5, it can be provided that the support body strip 32 is rolled into a bushing 35 by means of a rolling method, the first longitudinal end 33 and the second longitudinal end 34 of the support body strip 32 being brought closer to one another.

    the joint 23 can be integrally connected.
    In an embodiment variant in which the sliding layer 30 is already applied to the support body strip 32, it can be provided that the sliding layer 30 is removed in the region of the longitudinal ends 33, 34 either with the flat support body strip 32 or only when the bush 35 is rolled up, so that the longitudinal ends 33 , 34 of the support body stiffener 32 for the integral connection.
    are common. This process step can optionally also be omitted.

    In a further method step, the first longitudinal end and the second longitudinal end 33, 34 of the support body strip 32 can then be welded together at the joint 23. In a subsequent process step, the release 24 can be generated by mechanical removal, in particular by milling. In particular, in the exemption 24 the protruding material
    rial of the weld.
    If, as described above, the sliding layer 30 has already been sufficiently removed before the two longitudinal ends 33, 34 of the support body strip 32 are welded, this can optionally subsequently act as an exemption 24, as a result of which
    no further processing step is necessary for the welding process.
    In a further processing step, mechanical removal, in particular
    in particular by milling, the lubricant distribution groove 19 are generated.

    In an alternative embodiment variant, it can of course also be provided that
    that the groove base 36 of the lubricant distribution groove 19 does not run out into the outer circumferential surface 16, but rather the lubricant distribution groove 19 is designed in the form of a depression and the groove base 36 is thus seen in the circumferential direction
    Side walls is limited.
    The lubricant distribution groove 19 has a maximum depth 38, which is measured starting from an enveloping cylinder of the outer lateral surface 16. The maximum depth 38 of the lubricant distribution groove 19 can extend over a layer thickness 39 of the sliding layer 30. The diameter of the outer lateral surface 16 and the maximum depth 38 of the lubricant distribution groove 19 result in the
    Width 40 of the lubricant distribution groove 19.
    N2018 / 18900-AT-00
    The exemption 24 has a maximum depth 41, which is also measured from the enveloping cylinder of the outer circumferential surface 16 to a groove base 42 of the exemption 24.

This is the case if the maximum depth 41 of the exemption 24 in relation to the width 43 of the exemption 24 is selected to be so large that the groove base 42 of the exemption
    position 24 can not leak in the outer surface 16 of the plain bearing 22.
    As can be seen from FIG. 4, it can be provided that the maximum depth 38 of the lubricant distribution groove 19 is greater than the maximum depth 41 of the exemption 24. The maximum depth 41 of the exemption 24 is chosen to be as small as possible, so that as little as possible of the in the the lubricant distribution groove 19 of lubricant guided axially via the exemptions 24
    can give way.
    As can also be seen from FIG. 4, it can be provided that the width 40 of the
    Lubricant distribution groove 19 is larger than the width 43 of the exemption 24.
    In a further exemplary embodiment, not shown, it can of course also be provided that the sliding surface 17 and thus also the lubricant distribution grooves 19 are arranged on the inner lateral surface 15 of the sliding bearing 22.
