Product Description:
The original Deublin Rotary Union is available with part numbers 902-120-188, 902-121-188, 1101-195-343, and A10-1771-05L. It is specifically engineered for use in CNC spindle through-spindle coolant systems, ensuring efficient and reliable performance.
This rotary union features the patented Pop-Off seal technology, which allows the sealing faces to separate automatically without the need for fluid pressure. This innovative design supports unlimited dry running, enhancing the durability and longevity of the component.
Additionally, the unit incorporates a full-flow internal channel that effectively prevents swarf blockage. Its design is suited for use with water-based coolants as well as Minimum Quantity Lubrication (MQL) oil mist, making it versatile for various machining applications.
Features:
The pop-off seal design ensures a long service life, especially under dry running conditions. This feature enhances the durability and reliability of the equipment during extended use.
Equipped with a silicon carbide balanced mechanical seal, the product offers excellent resistance to wear and debris. This makes it highly suitable for demanding environments where contamination and friction are common issues.
The housing is made from anodized aluminum, providing both anti-corrosion properties and a lightweight structure. This combination helps to extend the lifespan of the component while keeping it easy to handle.
Stable rotation is achieved through the support of precision ball bearings, which can also tolerate minor misalignments. This ensures smooth operation and reduces the risk of mechanical failures.
Additionally, the labyrinth protection structure effectively prevents contaminants from reaching the bearings. This feature maintains optimal performance and reduces maintenance requirements.
The design incorporates a large single passage that allows for a sufficient flow rate and prevents clogging. This ensures consistent functionality without interruptions caused by blockages.
Installation is simplified with a direct spindle thread mounting system, making setup quick and hassle-free. This saves time and reduces the complexity of assembly.
The product is widely compatible with a variety of CNC machine tools, including popular brands such as DMG, Mazak, Brother, and Haas. This broad compatibility makes it a versatile choice for many industrial applications.
