Description
F 9.280 Rotary couplings, four passage

General description
Rotary couplings supply the pressure oil to rotating and swivelling installations. They are mounted in the centre of rotation of the installation.

Operating conditions
When selecting, operating pressure and speed have to be taken into account. Only use hydraulic oil of the viscosity classes 22, 32 and 46. 
The rotary coupling has to be connected to the power unit on all levels to ensure sufficient lubrications of the seals. 
The rotary couplings must only be used in a  temperature  range  between  + 10 °C and 
+ 60 °C. This also applies to possible special versions with FKM seals.
Operating conditions, tolerances and other data see data sheet A 0.100.
