Abstract
The invention relates to a tubular rotary joint, in particular for conducting a polymer melt, comprising a holder and a mobile connection body, which is rotatably connected to the holder by means of one bearing end. A distribution chamber with a feeder is configured in the holder, said chamber being connected to a distribution channel that is configured in the connection body. The distribution channel in the connection body leads to a connection end, to which a pipe section can be coupled. To guarantee the flexibility of the connection body at high pressure and at high temperatures, the bearing end of the connection body is configured as a shaft journal, which is rotatably mounted in a bearing bore that penetrates the distribution chamber in the holder.
