Deublin 1117-071 Rotary Union Equivalent | High-Speed Coolant Union Replacement

Description

Our Deublin 1117-071 rotary union equivalent is a high-performance replacement solution designed for coolant and MQL (Minimum Quantity Lubrication) applications in CNC machine tools and high-speed spindles.

Engineered to match the original Deublin specifications, this rotary union features a bearingless closed-seal design, ensuring reliable fluid transfer, reduced wear, and long service life under high-speed conditions.

The 1117 series is widely used in machining centers where high-pressure coolant delivery and high rotational speed are required to improve cutting efficiency and extend tool life.

As a professional manufacturer with over 10 years of experience in rotary union production, we provide a cost-effective and fully compatible replacement for Deublin models.
