A rotary joint or union characterized by its ease of assembly, disassembly and maintenance wherein a mounted internal condiut supports a rotary anti-friction bearing housing to which a seal housing is removably attached by bolts. A conduit port defined in the seal housing communicates with the interior of the conduit. A bearing retainer mounted upon the end of the conduit includes a seal having a radial face engaging the radial face of a seal mounted on the seal housing in a self-aligning manner. A compression spring maintains engagement of the seal faces through a seal assembly, and the seal housing seal is mounted within a retainer loosely keyed to the seal housing to facilitate self-alignment.
