Description

With five different designs to meet the needs of many different applications, Eaton Airflex Dual Passage Rotorseals transfer media through two separate passages on the same shaft end. With American National Pipe Threads on inlet and outlet ports, each passage can be used for a different medium, such as air for clutch actuation and oil for bearing lubrication.

Features

Type AD

• The 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.

Type ADP

•     The Type ADP rotorseal 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.

Type BD

• The BD is similar to the AD, except for a larger diameter mounting flange.
• The inner passage is sealed with a 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.

Type FDA

• The FDA type rotorseal is similar in design to the BD rotorseal, and has 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.

Type RD

• Designed to transmit actuating and cooling fluids.
• The RD can be used with mineral oil, water and air.
• The rotating seal is provided by a non-metallic sealing ring, held against the rotorseal shaft by a light spring force.
