A hydraulic rotary manifold has a core manifold having a barrel and a rotatable spindle inserted in the barrel. The core manifold is common to a variety of different configurations involving removable spindle-mounted and barrel-mounted manifolds, which may be removably mounted on the core manifold and exchanged for other removable manifolds to provide different hydraulic fluid flow paths in the rotary manifold using the common core manifold. The rotary manifold permits retrofitting a secondary fluid flow path to use a secondary fluid in conjunction with a work tool mounted on the rotary manifold. The rotary manifold permits mounting a rotary position encoder on a barrel-side of the rotary manifold permitting the use of the common core manifold when a rotary position encoder is desired. Electronically actuated cartridge valves may be integrated into the core manifold and/or removable manifolds to provide further customization of the hydraulic fluid flow paths in the rotary manifold and/or to provide cross-over relief paths within the rotary manifold itself.

A swivel joint comprises a tubular female member which is rotatably connected to a tubular male member. The female member includes a female race portion having an axially extending inner annular recess, a female inner end portion which is formed at an axially inner end of the recess, and a number of inner annular grooves which are formed in the recess coaxially therewith. The male member includes a male race portion having an annular outer surface which is configured to be received in the recess, a male nose portion which is formed at an end of the male race portion, and a number of outer annular grooves which are formed on the outer surface coaxially therewith. The male race portion is positioned in the female race portion such that the male nose portion is located adjacent the female inner end portion and each outer groove is aligned with a corresponding inner groove to thereby define a number of annular bearing races within which a plurality of balls are received to thereby rotatably connect the male member to the female member. The swivel joint includes a first primary seal which is positioned between the male nose portion and the female inner end portion, and a second primary seal which is positioned between the male nose portion and the female inner end portion radially outwardly of the first primary seal. The male and female members define a flow bore through the swivel joint which is sealed by the first primary seal and, in the event of a failure of the first primary seal, the second primary seal.
