SERIE SJ 90

Meccanica Borroni

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.
