Item # 145461AA, Single Passage Rotorseals


The Airflex rotorseal is a rotary union (rotary joint) which permits the transfer of gases or liquids, under pressure or vacuum, into or out of the exposed end of a rotating shaft or body. It was designed primarily for the passage of compressed air or hydraulic fluid to control clutches or brakes. Other applications include the transmittal of cutting fluid to machine tools, lubrication of shaft-mounted components and circulation of oil for cooling systems.

General Description
The rotating seal is established by a non-metallic sealing ring, held against the rotorseal shaft by a light spring force. The sealing ring is designed so that media pressure acts on both of its ends to minimize the force on the sealing surface.

This design gives positive protection against leakage and compensates for seal wear. Ball bearings are used between the stationary and rotating ports to provide rigidity to the rotorseal assembly and to minimize the running torque.

Rotorseals are available with single, dual and triple passages, in a variety of sizes and designs, to provide the versatility needed to handle most requirements. Single passage rotorseals, in pneumatic installation, can be plumbed with a quick release valve at its inlet port to provide a convenient exhaust.

In most applications, the rotorseal is mounted to the end of a shaft. The shaft is rifle and cross drilled to provide a passageway for the media transmitted. It is important that the rotorseal's axis of rotation be concentric with the rotating member's axis of rotation to minimize rotorseal wobble.

To accommodate eccentricities, a flexible connection must be used between the rotorseal and supply. A rigid connection will tend to preload the rotorseal bearings. The flexible connection should not be installed taut and should include a union and 45º elbow.

The flexible connection should be attached to the rotorseal prior to fastening the rotorseal to the rotating body to avoid seal or bearing damage. The union connection to the supply line is made last.
