Eaton Airflex Dual Passage Rotorseal

Eaton Airflex Dual Passage Rotorseal

Eaton Airflex rotor seals permit the transfer of gases or liquids, under pressure or vacuum, into or out of the exposed end of a rotating shaft or body. Rotor joints provide individual control of components mounted on the same shaft, component lubrication, and circulation of fluid systems.

Dual passage rotor-seals transfer media through two separate passages on the same shaft end. Each passage can be used for a different medium. For example, air for clutch actuation and oil for bearing lubrication. Developed in five different designs to meet the needs of many different applications.

1. Dual Passage Rotorseal - AD

• Features a 1/4"-18 inlet port for each of the passages.
• Both passage outlets can discharge directly into the shaft end.
• An optional 1/4"-18 outlet port in the mounting flange could be used for the outer passage.
• The inner passage nose is sealed on its outside diameter by a pair of "O" rings.
• The outer passage is sealed to the shaft end with a compression grommet.

2. Dual Passage Rotorseal - ADP

• Attaches to the shaft end with a 1"-11 1/2 thread outlet instead of a mounting flange.
• The outer passage outlet feeds into the end of the machine shaft.
• The inner passage is a 1/4"-18 port located on a flat of the hex mounting nut.

3. Dual Passage Rotorseal - BD

• Similar to the AD rotorseal, except for a larger diameter mounting flange.
• The inner passage is sealed with a flat rubber washer which compresses on the bottom of a counterbore in the shaft end.
• A compression grommet is used between the shaft end and mounting flange to seal the outer passage.

4. Dual Passage Rotorseal - FDA

• Similar in design to the BD rotorseal with larger passages.
• The two inlet ports and the two flange outlet ports for the outer passage are 1/2"-14.
• Compression grommets are used between the shaft end and mounting flange to seal the inner and outer passages.

5. Dual Passage Rotorseal - RD

• Designed to transmit actuating and cooling fluids.
• Used with mineral oil, water, and air.
• Supported by a non-metallic sealing ring, held against the rotorseal shaft by a light spring force.
