The Model 301 is a single pass fluid rotary union that can be operated as a stand alone FRU. Its design has been optimized to allow any standard AC4598 / AC6200 Moog electrical 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. This unit has been tested in excess of 80 million revolutions. The BSPP ports and mounting flange allow convenient fixturing against an O-ring sealed shaft or separate threaded conduit.
