Showa Giken RXE1025R Pearl Joint Rotary Union

Showa Giken RXE1025R Pearl Joint Rotary Union is a 1-inch NPT brass rotary joint from the Pearl RXE series, engineered to feed fluids to rotating sections of machinery without leakage. It features a simplex thread connection in a brass housing, with a rotor sealed by a ceramic seal ring and a carbon seal ring, and supported by ball bearings for durability at rotation. The RXE variant is lubrication-free, thanks to the combination of ceramic and carbon seals and ball bearings. It handles media such as steam, hot water, heated oil, and cooling fluids like water or brine, as well as ammonia or Freon, and can also convey compressed air or hydraulic oil to rotating equipment such as rolls, drums, cylinders, or chucks. Pearl rotary joints are designed to maintain stable seal performance across a range of service conditions, enabling reliable transfer of fluids from fixed piping to a rotating element. Typical RX-series applications include supplying heat transfer media or cooling fluids to rotating machinery in industrial settings, with the RXE1025R sized for mid-range installations and a maximum rotation speed up to 500 rpm, making it suitable for moderate-speed rotary unions in production lines.
