Overview & Technology:
The SHOWA GIKEN RXE Series Rotary Joint (Rotary Union), manufactured by SHOWA GIKEN INDUSTRIAL CO., LTD. (Japan), is a world-class fluid conveying solution engineered to connect stationary pipelines to high-speed rotating rolls without fluid leakage. Built with high-grade mechanical seal technology (Carbon, Ceramic, or Tungsten Carbide), the RXE series delivers exceptional sealing performance, low frictional resistance, and high durability under demanding industrial conditions.

Key Features & Highlights:
• Zero-Leakage Sealing: SHOWA GIKEN's precision mechanical seal design reliably prevents pressure drops and fluid seepage over long operational cycles.
• High Temperature & Pressure Versatility: Capable of handling a wide array of industrial media including saturated steam, hot water, thermal oil, coolant, and compressed air.
• Comprehensive Model Range:
  - Thread Direction Options: Available in Right-Hand (RH) and Left-Hand (LH) thread configurations to prevent loosening during forward or reverse cylinder rotation.
  - Flow Circuit Design: Covers both Simplex (single-passage RXE 1000 series) and Duplex (two-passage internal siphon pipe RXE 1100 / RXE 1200 series).
• Dual Precision Ball Bearings: Ensures smooth rotational stability, low vibration, and minimal start-up torque, reducing energy consumption on drive motors.

Durability & Heavy-Duty Construction:
The housing body is precision-machined from robust copper alloys and stainless steel adhering strictly to Japanese Industrial Standards (JIS). It provides outstanding resistance against thermal shocks, corrosion, and continuous mechanical wear without requiring frequent relubrication.

Practical Value for QA/QC:
Deploying SHOWA GIKEN RXE Series rotary joints effectively prevents unexpected production downtime caused by joint seal blowouts, maintains uniform cylinder roll surface temperatures, and maximizes manufacturing throughput.
