Description
RIX Rotary Union: Product Overview
Are you seeking a cost-effective, high-performance alternative to Rix Rotary Unions?
We are a specialized manufacturer of high-precision rotary unions designed to be 100% interchangeable with Rix series products. Engineered for the demanding environments of Deep Hole Processing (Gun Drilling) and high-speed CNC machining, our unions deliver the reliability you expect at a direct-factory price.
The RIX Rotary Union is a cutting-edge solution designed for efficient fluid transfer in various industrial applications. We engineer this rotary union for high performance and reliability, making it particularly well suited for ball screw cooling and other applications that require precise coolant management. With its innovative design and advanced features, the RIX Rotary Union enhances operational efficiency while minimizing energy consumption.
Key Features of Rix Rotary Union
Breakthrough in speed and pressure resistance
RIX rotary joints increase the normal working speed to 15,000/min through the built-in bearing structure design, and some models (such as LA-1P02) can reach 50,000/rpm under specific configurations. At the same time, its pressure resistance range covers 7-20MPa, far exceeding the industry average. Taking the LX84-7920 model as an example, this product is designed for machine tool spindle cooling scenarios. It can withstand 0.5-7MPa pressure in cutting fluid delivery to ensure a stable supply of coolant during high-speed cutting.
Innovation in sealing technology
We use silicon carbide sealing materials that provide excellent wear resistance and self-lubricating performance; consequently, the design supports ultra-high-speed dry operation and high-pressure coolant environments, enabling leak-free operation in ultra-high-speed dry applications (such as the ESX20M series) as well as in high-pressure coolant systems (such as the L40 series). Test data shows that under a pressure of 20MPa, its leakage is far lower than the industry standard.
Modular design to adapt to complex working conditions
RIX provides diversified solutions for different media requirements. It covers machine tool spindle cooling (supported by models such as LA-1P02 and LX86V-244C), semiconductor manufacturing (L40/MFES series), floating oil recovery, and other scenarios, meeting the transportation requirements of different media (cutting fluid, oil, dry air, pure water, etc.).
Bearing technology breakthrough
The built-in bearing structure design improves maintainability and service life, and solves vibration and leakage problems during horizontal use.

Application
CNC machining center
In high-speed cutting scenarios, RIX rotary joints withstand speeds of up to 50,000 r/min and, as a result, deliver cutting fluid to the spindle at a constant pressure, thereby preventing tool chipping caused by insufficient cooling.
Semiconductor manufacturing
The L40/MFES series rotary joints control the amount of metal ion dissolution at the ppb level through the non-metallic main channel design, meeting the ultra-clean requirements for pure water and chemical solution delivery.
Oil drilling
In drilling equipment, RIX rotary joints can withstand high-pressure and high-temperature environments, ensuring the stability of power transmission and signal control, and reducing the risk of drilling accidents.
Floating oil recovery system
The MOS series rotary joints use a spiral design to achieve efficient floating oil recovery in harsh environments such as sludge and slag, and the continuous working recovery volume can reach 100 ml/hr.

Installation Requirements for the RIX Rotary Union in Vertical Applications
Orientation
The RIX Rotary Union can be installed in both vertical and horizontal orientations. However, if installed vertically, the rotor should ideally point downward to prevent potential damage. Installing with the rotor pointing upward may lead to component failure due to fluid accumulation or leakage issues.
Connection of Hoses
Flexible Hoses: Always use flexible hoses for connecting the rotary union to avoid stress on the unit. This flexibility helps accommodate any movement and prevents lateral loads on the bearings, which can lead to premature wear.
Hose Installation: Ensure that hoses are installed without stress or bends. They should be routed in a way that allows for easy drainage of any leakage, particularly when the rotary union is positioned vertically.
Leakage Management
Install a leakage or ventilation line to manage any function-related leakage that may occur during operation. This line should be positioned at the lowest point of the installation to facilitate proper drainage.
If connecting hoses from above, consider installing a check valve (with a switching pressure of less than 0.5 bar) near the rotary union to prevent backflow during operation.
Pressure and Residual Pressure Checks
Before installation, ensure that there is no feed pressure or residual pressure in the pipeline system of the machine. This precaution is critical for safe and effective installation.
Axial Force Considerations
Be aware of axial forces that may need to be absorbed by spindle bearings, especially in housing-supported models. The medium pressure at the effective diameter can create additional axial forces that must be accounted for during installation.
Installation Manual Reference
Always refer to the model-specific installation manual provided with the RIX Rotary Union for detailed instructions tailored to your specific model. This manual includes vital information regarding connection configurations and operational guidelines.
