Abstract: The invention relates to a clutch hub. The clutch hub (1) comprises a hub body (2) with an axial passage opening (4) for receiving a shaft (5) and with in each case one face side (3a, 3b) at the two axial ends of the passage opening (4). An internal surface (6) is formed in the passage opening (4), and a flat surface (7a, 7b) annularly surrounding the passage opening (4) is formed on each of the face sides (3a, 3b). The internal surface (6) is covered by an electrical insulation coating (8) in the form of a ceramic coating. The electrical insulation coating (8) also, in continuous fashion, covers a respective annular region (9a, 9b), surrounding the passage opening (4), on the flat surfaces (7a, 7b) and a transition region (10a, 10b) formed between the internal surface (6) and the respective annular region (9a 9b).
