DEUBLIN 1116-090-143 3/8" NPT Single Passage Deublin Rotary Joint Incorporating Pop Off Balanced Silicon Carbide Seal Designed for Rotating Equipment Performance

Product Description:

The original Deublin Rotary Union, which includes models 902-120-188, 902-121-188, 1101-195-343, and A10-1771-05L, is specifically engineered for CNC spindle through-spindle coolant systems. This rotary union ensures efficient and reliable performance in demanding machining environments.

One of the standout features of this product is its patented Pop-Off seal technology. This innovative design allows the sealing faces to separate automatically without the need for fluid pressure, enabling unlimited dry running. This enhances the durability and operational flexibility of the rotary union.

Moreover, the internal channel is designed for full-flow, effectively preventing swarf blockage during operation. This makes the rotary union highly compatible with water-based coolants as well as Minimum Quantity Lubrication (MQL) oil mist, ensuring versatility across various coolant applications.

Features:

The seal structure features a Pop-Off design, ensuring a long service life even under dry running conditions. This enhances durability and reliability in various operating environments.

Equipped with a silicon carbide balanced mechanical seal, the system offers excellent resistance to wear and debris, contributing to its robust performance and extended maintenance intervals.

The housing is made from anodized aluminum, providing both anti-corrosion properties and a lightweight construction. This combination improves the overall lifespan and ease of handling.

Stable rotation is achieved through precision ball bearing support, which also tolerates minor misalignments. This design ensures smooth and consistent operation under different working conditions.

To protect the bearings from contamination, a labyrinth protection structure is incorporated. This feature helps to maintain the integrity and longevity of the internal components.

The large single passage design allows for a sufficient flow rate while preventing clogging issues, thus maintaining optimal performance and reducing downtime.

Installation is simplified with a direct spindle thread mounting, making it convenient and efficient to set up without the need for complex adjustments.

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