Water rotary joint RX®

for thermal oilmulti-passageprecision

The RX rotary union connects stationary piping to a rotating device. The fluid is sealed by précision, micro-lapped seals that provide a uniform, full-flow design. The union is supported bytwo widely-spaced anti-friction bearings and is available with a bearing isolation system for added bearing protection. The RX union is capable of intermittent dry running and features a 100% pure-molded carbon graphite or Silicon carbide seal and tungsten carbide counterseat.
