Rotorseals

 

Airflex rotorseals allow passage of pressurized fluids from a stationary inlet to a rotating shaft end. Single, dual and triple passage rotorseals are available in a variety of sizes and designs to meet most flow requirements. The multiple passage units can be used for individual control of components mounted on the same shaft, component lubrication and circulating fluid systems.

Dual Passage Rotorseal

 

Dual passage rotorseals allow the transfer of media thru two separate shaft passages located on the same shaft end. Each passage can be used for a different medium; for instance, air for clutch actuation and oil for bearing lubrication. Inlet and outlet ports have American National Pipe Threads. Airflex has five (5) dual passage rotorseal product lines.

 

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.

Single Passage Rotorseal

 

Single Passage Rotorseal

 

FEATURES:

 

Type RH

 

  • Created for applications that require a large flow, single passage rotorseal.

  • This design incorporates a mounting flange for attachment to the machinery shaft or assembly.

  • External American National Pipe Threads are provided on the inlet rotorseal shaft to facilitate supply line connections.

  • Port Sizes - 0.75", 1.0", 1.25", 1.50", 2.0"

 

Types AA2, B3 and C2

 

  • This group of rotorseals will handle most medium volume, single passage requirements.

  • External threads on the seal shaft and standard pipe threads on the inlet port make installations an easy job.

  • Housing Port Sizes - 1/8", 3/8", 1/2"

 

Internal Rotorseal

 

  • Created for applications where axial length is critical and space is not available for an overhung rotorseal.

  • The internal design and components of the Internal Rotorseal are the same as those used in the single passage rotorseals.

  • Port Sizes - 1/8", 3/8", 1/2"
