High-Pressure & High-Speed Capabilities

Designed to handle coolant pressures up to 105 bar and spindle speeds up to 15,000 rpm, ensuring stable performance under demanding machining conditions.

Full-Flow Internal Structure

Built with an unobstructed flow path to prevent debris accumulation, ensuring continuous coolant delivery and improved chip evacuation.

Bore-Mounted Configuration

Compact bore-mounted design allows for easy installation directly into CNC spindles, reducing setup time and ensuring reliable alignment.

Balanced Mechanical Seals

Equipped with silicon carbide balanced seals that withstand abrasive coolant media and ensure long-lasting, leak-free operation.

Labyrinth Bearing Protection

Protects the bearings from coolant contamination, extending service life and reducing maintenance costs.

Hybrid Precision Bearings

Utilizes ISO Class P4 hybrid ball bearings (steel races with ceramic balls) for smooth rotation at high speeds, reducing heat buildup and wear.

Corrosion-Resistant Construction

Features anodized aluminum housing and stainless-steel components, offering superior resistance to rust and coolant-induced corrosion.

Temperature Resilience

Operates efficiently in environments up to 71°C (160°F), maintaining seal integrity and performance during continuous operation.

Cost-Effective Alternative

Provides equivalent performance to the original Deublin 1114-308-188 rotary union at a more competitive price, making it an ideal choice for cost-conscious manufacturers.

Applications

Automotive Industry – High-speed machining of crankshafts, camshafts, and fuel system components.
Aerospace Industry – Deep hole drilling, precision boring, and high-speed milling of turbine shafts, landing gear, and structural parts.
General Machining – CNC milling, drilling, and turning where dual-channel coolant and air service are required.
Oilfield & Energy Equipment – High-precision boring and machining of hydraulic components and drilling tools.

Advantages of Using a Dual-Channel Rotary Union

Flexibility in Media Transfer

Dual-channel design allows delivery of coolant and compressed air through the same rotary union, reducing the need for separate connections and improving efficiency.

Improved Tool Life

High-pressure coolant ensures better lubrication and cooling at the cutting edge, significantly extending tool life and reducing replacement costs.

Enhanced Surface Finish

Consistent coolant flow prevents tool overheating, leading to smoother bore finishes in deep hole drilling and precision machining.

Reduced Downtime

With robust sealing technology and labyrinth bearing protection, this rotary union requires less frequent maintenance, keeping production running smoothly.

Lower Operating Costs

As a cost-effective alternative to the OEM Deublin 1114-308-188, it provides the same high-performance reliability at a reduced investment.
