Abstract
A process for the production of a sleeve shaped friction bearing including the steps of producing a thin inner sliding layer of a polymeric material free of abrasive fillers on a core by a molding process, producing a longitudinal interruption in an outer surface of the sliding layer from one end to another, and sheathing the inner sliding layer with an outside support of another polymeric material and joining the inner layer with the outside support by filling the interruption.

Process for the production of a sleeve-shaped friction bearing having a longitudinal axis of rotation and with an inner sliding surface facing toward the axis of rotation, a thin, inner sliding layer made of a polymeric material having good sliding properties, and a support surrounding said sliding layer which is made of a polymeric material, the sliding layer having a depression which faces toward the support, and which is filled with the material of which the support is made, comprising the process steps of:
- A) producing the thin, inner sliding layer a first polymeric material that is free of abrasive fillers on a core by a molding process;
- B) producing at least one longitudinal interruption in an outer surface of the sliding layer which extends from a first axial end to an opposite axial end of the inner sliding layer with said at least one longitudinal interruption in the outer surface of the sliding layer only partial separating the sliding layer with an underlying web connecting portions of said sliding layer at opposite sides of said longitudinal interruption;
- C) sheathing the inner sliding layer with an outside support made of a second polymeric material while said inner sliding layer is on said core and joining the inner sliding layer with the outside support in a manner filling said longitudinal interruption with the second polymeric material of the outside support so as to dimensionally stabilize the sliding layer;
- and
- D) pushing the sheathed and dimensionally stabilized sliding layer off of said core and then discarding the core.
