2-in 2-out High-Temperature Water-Cooled Slip Ring
This 2-in/2-out high-temperature fluid rotary union is engineered for demanding temperature environments. Featuring a through-hole design with black aluminum alloy housing and an inner diameter of 50mm, it reliably transmits fluids such as water and air simultaneously. The unit supports an extreme operating temperature range of -30°C to +120°C, maximum working pressure of 1MPa, and IP51 protection rating. Ideal for wide-temperature range fluid circulation and pneumatic control in food processing, chemical reactions, high-temperature cleaning, and other industrial applications.
Key Features
- Wide Temperature Range: Operates stably from -30°C to +120°C, adapting to process requirements from cryogenic cooling to high-temperature steam/hot water applications
- Dual-Medium Synchronous Transmission: Two independent channels support simultaneous circulation of various fluids and gases including water, air, and heat transfer oil
- 50mm Large Inner Bore: Through-hole design provides ample central space for wiring and rotating shafts, optimizing equipment layout
- High-Pressure and High-Temperature Resistant: Special sealing solution ensures leak-free operation under wide temperature differences up to 150°C and 1MPa pressure

Frequently Asked Questions
Is the product suitable for steam media?
Yes. The upper working temperature limit of +120°C allows it to be used for saturated steam transmission under certain pressures. Specific selection and confirmation based on steam temperature and pressure parameters are required to ensure the long-term compatibility of the sealing materials.
Will the sealing material become brittle and fail under low-temperature conditions (e.g., -30°C)?
No. The low-temperature sealing materials used in the product (such as fluororubber, special silicone rubber, etc.) have excellent low-temperature flexibility and resistance to cold embrittlement. They are specifically designed for a wide temperature range, ensuring reliable sealing performance even in continuous low-temperature environments.
Besides passing wires, can a rotating shaft pass through the 50mm inner bore?
Yes. One of the main uses of the 50mm through-hole design is to allow the rotating main shaft of the equipment to pass through it, achieving a true "shaft-in-shaft" structure, which is particularly suitable for equipment requiring central drive, such as mixers and roller presses.
