Six Passages

7500 psi max
CARACTÉRISTIQUES: Ideal for supplying fluid to rotating or swivelling fixtures. Rotary Couplings are the best option for feeding fluid to rotating pallet changers, due to the continuous fluid connection. Also ideal for rotary index tables.
MODÉLES DISPONIBLES: Six-passage couplings are available only with the leakage-recirculation option. This version with leakage recirculation has an additional port L for recycling the slight amount of fluid lost due to internal bearing leakage — see Dimensions page for part number. For special Rotary Couplings, including variations for manifold mounting or for applications with low operating pressures, please contact factory.
MONTAGE: Mount at rotational centre to prevent side loading. Fasten either the top or the bottom of the coupling using the tapped holes provided. Alternatively, if the coupling has steel tubing lines, fastening is not absolutely required, although an anti-rotational key is adviced. Do not use NPT fittings.
CONSIDÉRATIONS DE CONCEPTION: In applications with rotary tables, the fluid pressure in the coupling will increase the table's starting-torque requirement and affect maximum rotation speed (see graph). All fluid-supply passages must be connected the power source, to ensure sufficient lubrication of the seals (do not turn the coupling while dry, even before installation). Use only with clean hydraulic fluid (10 micron or better nominal filtration). Use either standard hydraulic fluid (CLR-2-FL) or other hydraulic fluid of the viscosity classes HLP 22, 32, or 46. Allowable operating-temperature range is 50 to 140°F. |
