The 2-channel thermal oil slip ring is a dual-channel rotary joint specifically designed for high-temperature heat transfer fluids. It features a black aluminum alloy housing with a 50mm inner diameter and a 119mm outer diameter through-hole structure. Equipped with two independent G1/4" interfaces, it is specifically designed for transferring high-temperature heat transfer media such as thermal oil.
It can withstand a maximum pressure of 1MPa, a maximum speed of 150rpm, and an operating temperature of up to 180℃, and has an IP51 protection rating. It is a core component for rotary heating or cooling in equipment such as rubber and plastic machinery, reaction vessels, and hot presses.
Key Features
180℃ High-Temperature Design: Utilizing high-temperature resistant sealing materials and special lubrication technology, it can operate stably for extended periods in high-temperature heat transfer oil environments up to 180℃, eliminating the softening and failure issues common with ordinary seals at high temperatures.
50mm Large-Diameter Hollow Structure: The 50mm central through-hole allows heating rods, thermocouples, power lines, or drive shafts to pass through, providing significant flexibility for equipment integration.
Dual-Channel Independent Circulation: Two independent G1/4" interfaces can be used as the inlet and outlet of the heat transfer oil respectively, forming a complete thermal circulation loop, or for two independent heating zones.
Excellent High-Pressure Sealing Performance: Under 1MPa pressure and high-temperature conditions, a specially designed rotary seal ensures leak-free long-term operation, guaranteeing production safety and thermal efficiency.
Rugged and Durable Industrial Design: The black aluminum alloy housing provides excellent heat dissipation, and the IP51 protection rating effectively prevents dust and drips, making it suitable for industrial workshop environments.

Frequently Asked Questions
Q1: Does the maximum operating temperature of 180℃ include the peak value of instantaneous fluctuations in the heat transfer oil?
180℃ is the recommended stable temperature for long-term continuous operation. The product can withstand brief peak overheating, but prolonged exposure to this temperature will affect the lifespan of seals and bearings. For higher temperatures (e.g., 250℃), we can provide customized high-temperature models.
Q2: Can a rotating shaft pass through a 50mm inner diameter?
Yes. A 50mm inner diameter can accommodate rotating shafts with a diameter less than 45mm, allowing for integrated installation of the equipment's main shaft and slip ring.
Q3: Can the product transfer other heat transfer media besides heat transfer oil?
Yes, but compatibility needs to be confirmed. Standard seals are suitable for mineral-based heat transfer oils. For transferring other high-temperature media such as water-glycol, steam, or molten salt, please provide the specific parameters of the media, and we will select the most suitable sealing material for you.
