Dual Passage Rotorseal

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

  • A 1/4″—18 inlet port services each of the passages
  • Optional 1/4″—18 outlet port in the mounting flange can be used for the outer passage
  • Both passage outlets can discharge directly into the shaft end
  • 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

Features Type ADP

  • Attaches to the shaft end with a 1″—11-1/2 thread outlet instead of a mounting flange
  • TOuter passage outlet feeds into the end of the machine shaft
  • Inner passage is a 1/4″—18 port located on a flat of the hex mounting nut

  • A Compression grommet between the shaft end and mounting flange seals the outer passage

Features Type FDA

  • Similar in design to the Eaton Airflex Type BD but has larger passages
  • Two inlet ports and two flange outlet ports for the outer passage are 1/2″—14
  • Compression grommets between the shaft end and mounting flange seal the inner and outer passages
