A plain bearing bushing is formed from a material strip, wherein a first joining end of the material strip has a projection and a second joining end has a recess interacting with the projection, a base side of the projection being oriented towards the first joining end. A bushing is to be provided that is designed to be more advantageous with respect to the production method, in particular during the forming process, and with respect to dimensional tolerance and long-term stability. This is achieved by a bushing with clamping elements in which the joining ends of the material strip are fixed both in axial direction and in circumferential direction of the bushing in a frictionally engaged and/or formfitting manner.

Bushing

A collar bearing comprising a bearing shell and at least one thrust washer, whereby the at least one thrust washer is fixed on an outer convex circumferential surface of the bearing shell to define a joint site that extends between the convex outer circumferential surface of the bearing shell and a concave inner circumferential surface of the thrust washer, the at least one thrust washer being welded along a weld seam to the bearing shell such that the weld seam extends axially between an outer thrust facing and an opposite inner surface of the at least one thrust washer, and the weld seam extends over only a part of the joint site.

Welded collar bearing method for producing welded collar bearings and a device for carrying out said method

A flange sleeve comprising at lest one flange formed thereon, having no gap at the joint or having a controllably adjusted width of the gap at the joint. The flange has two crowding recesses at least in the metal coating thereof in at least two points distributed over the flange in the direction of the periphery. According to the method for producing the flange sleeves, the edge of the flange is bent. At least two crowding recesses in at least two points distributed over the flange in the direction of the periphery are made at least in the metal coating thereof, the recesses preferably being made by bending the edge of the sleeve. The invention also relates to a bending tool and a bending device.

Flange sleeve, method for the production thereof and bending tool for producing flanges on a sleeve

A bearing bush that can be installed without any auxiliary components and ensures a secure fit has a backing which comprises at least one layer, an overlay (,), on its inner surface and at least one flange (,) in the form of a circumferential closed bead provided at a distance from the bush ends. The bearing bush is suitable, inter alia, for flexible joints and pedal bearing systems. The method of producing such a bush takes as its starting point a prefabricated bearing bush (,), the inner surface of the backing (,) of which is exposed in at least one area (,) spaced from the bush ends. An internal mandrel is inserted into the bearing bush (,) and the bearing bush is held around its outer surface, at least one gap (,) being left opposite to the exposed area (,). The bearing bush is then compressed in the axial direction, the material is thereby displaced into the gap (,) to form the flange (,).

Bearing bush with center flange

A bearing bush (1) having a groove (7) which has a curved contour and is located inside an annular bead (2) projecting outwards with respect to the bush body (6). A sealing member in the form of an o-ring (4) may be inserted into the groove (7). The bead for accommodating the sealing member is produced by an upsetting process.
