    Abstract: The invention relates to a viscous coupling 1 having a housing 2 consisting of a tubular housing casing 3, and end walls 4, 5 extending radially relative to the longitudinal axis 9. Furthermore, the viscous coupling 1 comprises a hub 11 which is manufactured from a tube in a non-chip producing forming operation and which, by means of bearing faces 13 and 14, is relatively rotatably supported in the end walls 4, 5 of the housing 2. The inner toothing 10 of the housing 2 non-rotatably accommodates outer plates 35. Inner plates 36 are non-rotatably associated with the hub 11 so as to alternate with the outer plates 35. The inner plates 36 are received in the outer toothing 15 of the hub 11. The hub 11 also comprises inner toothing 30 to provide a non-rotating connection with corresponding outer toothing 29 of a shaft 28.
