This special rotary-joint configuration combines the PISCO Rotary Joint and High Rotary Joint families with a reverse-thread screw arrangement for rotating machinery.
The rotary joint platform uses a push-in tube connection and a bearing-supported body. The reverse-thread special version changes the screw direction so the threaded connection is less prone to loosening under the specified clockwise-rotation condition.
The PISCO Rotary Joint and High Rotary Joint families specify air service, 1.0MPa maximum operating pressure, -100kPa maximum vacuum and 0 to 60℃ operation. Tube sizes range from φ4 to φ12 with metric, taper, UNF and NPT interfaces by model.
Choose the reverse-thread version only where the rotation direction and thread arrangement match the machine. Verify the exact model and tightening direction before installation.
