Fluid Rotary Union
Model 301
Single Pass Fluid Rotary Union
The Model 301 is a single pass fluid rotary union. It can be operated as a stand alone FRU. Its design has been optimized to allow an AC4598 / AC6200 electric slip ring (ESR) to be mounted directly on the Model 301 body, simplifying the integration and mounting arrangement.
The Model 301 utilizes sealed-for-life rolling element bearings to provide long trouble free service. Filled PTFE based seals run on a hardened surface to provide long service life, minimizing frictional heat generation and operational torque. The BSPP ports and mounting flange allow convenient fixturing against an O-ring sealed shaft or separate threaded conduit.
Features
- 1-1/2” body O.D. to mount AC4598 / AC6200
- Optional torque arm (required for L.H. rotation) matches AC4598 / AC6200 torque arm allowing a single anti rotation interface
- 1 pass with 1/2” BSPP ports
- Rated to 145 psi [10 bar] at 250 rpm continuous service
- Maximum working pressure 180 psi [12.5 bar]
- Maximum recommended speed 2000 rpm (intermittent or with sufficient medium flow to cool assembly)
- Optional IP65 seal available
- Stainless steel version available as special order
Benefits
- Continuous 360º rotation
- FRU transfers air, oil, other non-corrosive medium
- Provides long maintenance free service
- Convenient mounting of FRU / ESR combination

Please note that operational life of the unit is dependent upon rotational speed, environment and temperature. Flexible conduit should be used on the torque are end to avoid side loading, which can shorten operational life.
