High Performance 50mm Dual-Passage Rotary Joint (Rotary Union) in 304 Stainless Steel

Are you looking for a reliable solution to transfer fluid between stationary pipes and rotating machinery? Our 50mm Bore Rotary Joint​ is engineered to solve the challenges of high-pressure leakage and premature wear in industrial environments. Designed specifically for water, coolant, and low-viscosity hydraulic oil, this unit ensures uninterrupted performance for your critical equipment.

Precision Engineering for Demanding Applications

Unlike standard carbon steel joints that rust and fail, this Rotary Union​ is constructed from premium 304 Stainless Steel. This provides superior resistance against corrosion, making it ideal for humid factory floors or cooling systems. With a robust design rated for ≤10MPa (1450 PSI)​ and a temperature tolerance of ≤80°C, it delivers stable power transmission even at speeds of ≤100 RPM.

Key Technical Advantages:

  • Dual Passage Efficiency:​ Features two independent flow paths (2-way), allowing simultaneous inlet and outlet flow. This is perfect for closed-loop cooling systems where both supply and return are required.
  • Zero-Leakage Guarantee:​ Equipped with high-precision bearings and advanced sealing technology to prevent drips, protecting your machinery from water damage.
  • Extended Service Life:​ The 304SS body combined with a balanced rotor design minimizes vibration, reducing maintenance costs and downtime.

Product Specifications:

  • Model:​ 50mm Dual Passage Rotary Joint
  • Material:​ 304 Stainless Steel
  • Working Pressure:​ Max 10 MPa
  • Speed:​ Max 100 RPM
  • Temperature:​ Max 80°C
  • Medium:​ Clean Water, Coolant, Air

Versatile Applications

This industrial rotary joint​ is widely used in:

  • Plastic Machinery:​ Calender roller cooling.
  • Metal Processing:​ Rolling mill cooling systems.
  • Automation:​ Rotary tables, winding machines, and robotic arms.
  • Thermal Equipment:​ Compatible with heating units requiring fluid circulation.
