ABSTRACT:
A hollow rotary member such as a roller, extruder or the like, requiring constant temperature control by a fluid circulating therethrough, has a hollow shaft with radial inlet and outlet ports communicating with respective compartments of a stationary coupling sleeve surrounding same, the compartments being bounded by sealing rings engaging the shaft. In order to facilitate the introduction of the shaft into the sleeve without damage to the sealing rings, the shaft ends in an extremity of reduced cross-sectional area whose noncircular outline consists of convex sections smoothly merging into one another.
