Abstract:
The invention relates to a method for producing a bearing component (1), in particular a connecting rod (1), from a molded part (2), wherein the bearing component (1) includes at least one divided bearing seat (5) formed by a bearing base (3) and a bearing cover (4), and a bearing seat surface (7) coated with a bearing layer (6) of a bearing layer material is formed in the bearing seat (5) for supporting a shaft. In the method of the present invention the bearing cover (4) is separated from the molded part (2) along a separating surface (8). In accordance with the invention, a masking agent (M) is disposed perpendicularly with respect to a separating line (10) on the bearing seat surface (7) during a coating process for applying the bearing layer (6) in order to form a coating-free region, such that a recess (9) at a predetermined width (B) is produced in the bearing layer (6). The masking agent (M) is formed as an element which is separate from the bearing component (1) and is not connected thereto. The invention also relates to a device for carrying out an efficient and cost-effective production method for coated bearing components.
