Instead of only matching the model number, Dann Hydraulic evaluates the complete operating condition to provide a suitable replacement solution.

Replacement Solution for Deublin 1116-048-143

The Deublin 1116-048-143 rotary union is commonly used in machine tool applications requiring coolant or minimum quantity lubrication (MQL) transmission.

Typical operating problems that require replacement include:

• Rotary union leakage
• Seal wear
• Bearing failure
• Machine downtime
• Spare parts availability issues

Dann Hydraulic provides replacement rotary unions based on:

• Original model number
• Technical drawings
• Installation dimensions
• Physical samples
• Machine operating parameters

Product Specifications

Final specifications should be confirmed according to actual working conditions.

Designed for CNC Coolant and MQL Applications

Modern CNC machining equipment requires stable coolant delivery during high-speed spindle operation.

A suitable rotary union helps maintain:

• Continuous coolant supply
• Stable pressure transmission
• Reduced leakage risk
• Improved machining reliability

The rotary union transfers coolant or MQL fluid from the stationary supply system into the rotating spindle while maintaining sealing performance.

Key Features of Replacement Rotary Union

Single Passage Fluid Transfer

The single passage design is suitable for:

• Coolant systems
• MQL lubrication systems
• Machine tool applications

It provides a direct flow path between stationary and rotating components.

Reliable Sealing Structure

Rotary union performance mainly depends on sealing technology.

Dann Hydraulic selects sealing solutions according to:

• Fluid type
• Pressure
• Rotation speed
• Temperature
• Duty cycle

This helps improve service life and reduce unexpected leakage.

Precision Machined Components

CNC machine tool applications require accurate dimensions.

Our manufacturing controls:

• Rotor dimensions
• Thread accuracy
• Housing tolerance
• Sealing surface finish
• Assembly precision

Common Problems with CNC Rotary Unions

Leakage During Operation

Possible reasons:

• Seal wear
• Incorrect installation
• Contaminated coolant
• Excessive pressure
• Shaft runout

Solution:

Evaluate the complete application and select the correct sealing configuration.

Short Service Life

Possible causes:

• High spindle speed
• Poor coolant quality
• Incorrect alignment
• Bearing overload

Solution:

Confirm actual machine conditions before replacement.

Incorrect Replacement Selection

A rotary union replacement requires checking:

• Thread specifications
• Rotor dimensions
• Installation length
• Media
• Pressure
• Speed

Matching appearance alone is not enough.
