Deublin 1109-023-212 1109-040-388 Rotary Union

Description

Product Overview

The Deublin 1109-040-388 Rotary Union is a high-precision single-passage pneumatic rotary joint engineered for stable and efficient air transfer in high-speed rotary systems. Our compatible model is specially optimized for textile machinery, including spinning, winding, dyeing, drying, and automated yarn-processing equipment.

Designed to match the performance of the original Deublin rotary union, this product provides smooth rotation, reliable sealing, and long service life, even under the demanding conditions of textile production lines. It ensures clean, consistent airflow to air shafts, actuators, and rotating components, helping textile manufacturers improve process efficiency and reduce machine downtime.

Key Features

Single-Passage Design for Coolant or MQL

This rotary union features a high-efficiency single passage, engineered specifically for coolant or Minimum Quantity Lubrication (MQL) systems. It ensures consistent media flow, stable pressure, and reliable lubrication performance during high-speed machining operations.

Full-Flow, Unrestricted Internal Passage

The internal full-flow design eliminates obstructions, preventing the buildup of swarf, chips, or debris. This maintains optimal flow efficiency, minimizes clogging, and improves system performance in heavy-duty machining environments.

Bearing-Supported Structure with Threaded Rotor

The union’s bearing-supported configuration and threaded rotor offer exceptionally easy installation and stable operation. This structure enhances radial load capacity and ensures precise alignment during high-speed rotation.

Dual Angular Contact Ball Bearings

Built with dual angular contact ball bearings, the unit provides superior load handling, excellent rotational stability, and extended service life. It performs reliably even under high RPM, high-pressure coolant, or demanding spindle speeds.

Labyrinth System with Large Venting for Bearing Protection

A robust labyrinth sealing system combined with large ventilation channels effectively protects the bearings from coolant, dust, and external contaminants. This significantly enhances bearing longevity and reduces maintenance frequency.

Silicon Carbide Mechanical Seals for Long-Lasting Performance

The rotary union incorporates balanced mechanical seals made from silicon carbide, known for their outstanding hardness, thermal stability, and wear resistance. These seals deliver long operational life even in severe coolant conditions or continuous-duty applications.

Corrosion-Resistant Anodized Aluminum Housing

Featuring a high-quality anodized aluminum housing, the union provides excellent corrosion resistance, lightweight construction, and improved durability. It is ideal for use in environments exposed to coolants, lubricants, or moisture.
