Rotorseal Description Cross Drilling Description The Airflex rotorseal is a rotary union (rotary joint) which permits the Rotorseal 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 Rifle Drilling machine tools, lubrication of shaft-mounted components and circula- tion of water or oil for cooling systems. 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. Typical Shaft Drilling This design gives positive protection against leakage and compensates for seal wear. Ball bearings are used between the stationary and rotat- ing ports to provide rigidity to the rotorseal assembly and to minimize the running torque. To accommodate eccentricities, a flexible connection must be used be- Rotorseals are available with single, dual and triple passages, in a vari- tween the rotorseal and supply. A rigid connection will tend to preload ety of sizes and designs, to provide the versatility needed to handle the rotorseal bearings. The flexible connection should not be installed most requirements. Single passage rotorseals, in pneumatic installa- o taut and should include a union and 45 elbow as shown. tion, can be plumbed with a quick release valve at its inlet port to pro- vide a convenient exhaust. In most applications, the rotorseal is mounted to the end of a shaft. Rotorseal Wobble The shaft is rifle and cross drilled to provide a passageway for the me- dia transmitted. It is important that the rotorseal�s axis of rotation be Axis concentric with the rotating member�s axis of rotation to minimize of rotorseal wobble.

J-12 BTA Triple Passage Rotorseal Form RS 907 Dimensional and Technical Data Type BTA The BTA rotorseal was designed for simultaneous transfer of as many as three different fluids. A mounting flange simplifies installation to the shaft end. Three 1/2-14 American National Pipe Thread inlet ports on the side of the stationary rotorseal body provide access to the concentric fluid pas- sages. All three passages can discharge directly into the rotating shaft. However, a 1/2-14 port in the mounting flange can be used as an optional outlet for the outermost passage.

J-14 RT Triple Passage Rotorseal Dimensional Data Airflex RT Triple Passage Rotorseals� are designed to simultaneously transfer three different fluids (or combination of fluid and gases) into or out of machinery through a rotating shaft or body. The RT Rotorseal has two 1" and one 0.5" diameter passageways and is available in a standard cast iron shaft design or a corrosion-resistant model with a brass shaft. These heavy-duty units were designed primarily for the passage of fluids to water-cooled clutches. Other applications include the transmittal of cutting fluid to machine tools, lubrication of shaft-mounted components and circu- lation of water or oil for cooling systems. The rotating seal is provided by a non-metallic sealing ring, held against the rotorseal shaft by a light spring force. The design promotes positive protection against leakage and minimal 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.

J-16 Typical Rotorseal Shaft Mountings Types AD, BD, FDA, & BTA Dual Passage Rotorseal The diagrams on the right illustrate typical shaft drilling for fluid passages. In the top diagram, one outlet is required out- board of the shaft support bearing. This outlet can be the one provided in the mounting flange of the rotorseal. The second outlet, between the shaft bearings, requires an axial hole and cross drilling. In the bottom diagram, both outlets are between the shaft bearings. A bayonet assembly, consist- ing of a length of steel tubing properly supported at both ends, is inserted into the axial hole. One passage is formed by the outside diameter of the tube and the wall of the axial hole. The inner pas- sage is the inside diameter of the tube. Rubber grommets are used at the inner bayonet support to seal the passages from each other.
