Product Description:

The original Deublin Rotary Union includes several key components such as the 902-120-188, 902-121-188, 1101-195-343, and A10-1771-05L models. This union is specifically designed for CNC spindles that utilize a through-spindle coolant system, ensuring efficient and reliable performance during machining operations.

One of the standout features of this rotary union is the incorporation of patented Pop-Off seal technology. This innovative design allows the sealing faces to separate automatically without the need for fluid pressure, which significantly enhances the system's durability. As a result, the rotary union supports unlimited dry running, minimizing wear and maintenance requirements.

Furthermore, the rotary union is equipped with a full-flow internal channel that effectively prevents swarf blockage. This feature makes it highly suitable for use with water-based coolants as well as Minimum Quantity Lubrication (MQL) oil mist systems, providing versatile compatibility for various machining applications.

Features:

The pop-off seal structure is designed to ensure a long service life, even under dry running conditions. This feature enhances durability and reliability during extended use.

Equipped with a silicon carbide balanced mechanical seal, the device exhibits excellent resistance to wear and debris. This helps maintain optimal performance and reduces maintenance requirements.

The housing is made from anodized aluminum, offering both anti-corrosion properties and a lightweight build. This combination improves the overall durability while keeping the unit easy to handle.

Stable rotation is supported by precision ball bearings, which can tolerate minor misalignments. This ensures smooth operation and longevity of the rotating components.

To protect the bearings from contamination, a labyrinth protection structure is implemented. This design effectively prevents debris from entering and damaging critical parts.

The large single passage design allows for a sufficient flow rate and provides excellent anti-clogging performance, ensuring efficient operation.

Installation is simplified through direct spindle thread mounting, making setup quick and straightforward.

This product is widely compatible with various CNC machine tools, including DMG, Mazak, Brother, Haas, and others, making it a versatile choice for different applications.
