The swivel joints of the SJHD series are designed to be mounted between a movable flexible hose and a rigid component of a machine
in order to allow and compensate rotations: the movement of the stem on his own axis prevents hose damages.
Compared with standard SJ series they have the following differences: - a greater length to share in a better way the radial loads on the
rotating stem; - a straight roller bearing assembled on the stem to reduce friction during the motion of rotation also with high working pressures;
- two seals instead of one for a higher reliability. They are used in every productive sector where there are means,
equipment or plant with moving flexible hoses working with high pressures inside.
Rotating system: on two balls-races and on one straight roller bearing
