Types of Rotary Joints and Unions
1. Single-Passage Rotary Joints
- Used for one-way transfer of fluids(steam, water or air).
- Common in paper mills, textile plants and in printing machines.
2. Multi-Passage Rotary Unions
- Permits passage of diverse fluids or gases, through one joint.
- Utilized in the CNC machinery, aerospace, and industrial automation sectors.
3. Steam Rotary Joints
- Applied in high-temperature and high-pressure environments.
- Found in chemical process industries, power plants, and textile industries.
4. Hydraulic Rotary Unions
- Responsible for the management of high-pressure oil or hydraulic fluid.
- Present in construction machinery, hydraulic presses, and cranes.
5. Air and Gas Rotary Joints
- Involved with the transfer of compressed air, vacuum, or inert gases.
- Found in pneumatic systems and robotics.
6. Coolant Rotary Unions
- Designed for the transfer of coolant or water in CNC and machining operations.
- Lowers friction and overheating in high-speed applications.
