ROTATING JOINTS FOR HYDRAULIC OIL AND AIR

 

 This two  ways rotating joint allowes the  free rotable angular position of radial outlet port when rotor is screwed. The rotor is made in cemented carbon steel and lapped for reducing friction and increase life of seals. The seals are made of PTFE. The external body is machned from aluminium bar to avoid any porosity, while the alignment of unit is given by a ball bearing and a self-lubricanting bushing of sinter-bronze. There is a threaded hole (DR) in the external body to avoid flow from first to second way.

 

Avoid working with maximum speed and maximum pressure.
