SK type high-temperature heat transfer oil rotary joint is a spherical sealed mechanical connection device designed specifically for heat transfer oil media. The core adopts dual carbon graphite oil-free bearings with automatic centering and convex spherical multi spring compensation sealing structure

The SK series rotary joint is a rotary joint used for thermal oil media. It uses two carbon graphite oil-free bearings to achieve automatic concentricity, ensuring long service life even if the rollers are not concentric. The selection of convex spherical sealing rings and optimized sealing dimensions has increased the sealing life of SK series rotary joints and greatly reduced maintenance costs. The SK series rotary joint is suitable for specifications ranging from 3/4 “to 8”, with single and double pass structural forms.

High temperature alloy spring, impregnated with antimony spherical sealing ring, can be used for a long time at high temperatures
Supported by double cylindrical oil-free bearings, the rotation is more stable and can be used for large vibration equipment
Anti spherical sealing design, four times stronger than ordinary seals, built-in anti impurity structure, longer lifespan
No maintenance required, easy to maintain;

Design features
Durable convex sealing design, faster operating speed
Multi spring compensation mechanism provides stable spring force for the sealing surface
Inlet/outlet flange connection, easy to install, disassemble, and maintain
Two carbon graphite bearings with widened spacing improve the self-supporting properties of the joint and inner tube
According to requirements, special products with sizes of DN300 and above can be designed and provided, and customized for customer equipment

Important Note:
1. The inlet and outlet pipelines must be connected using metal hoses;
2. The installed rotary joint must be able to move back and forth freely and swing left and right
Move at a certain angle and strictly prohibit fixing the rotating joint firmly;
3. The bi-directional fixed inner pipe threads are all right-handed, even if the outer pipe “K” is a flange or
Left threaded connection;
