Product Information

Rotary Couplings, F9.280 (Six Passage) Part # CLR-9286-135 Carr Lane Mfg.®

7250 psi max

Ideal for supplying fluid to rotating or swiveling 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.

Data Sheet

Models Available

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 additional passages, please contact factory.

Design Considerations

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.

Mounting

Mount at rotational center to prevent side loading. Fasten either the top or the bottom half of the coupling (but not both) using the tapped holes provided. If the coupling has steel tubing lines, fastening the other half is not absolutely required, although an anti-rotational key is recommended. Do not use NPT fittings.
