A08-1501-05L Rotoflux Rotary Union for Coolant Delivery Through the Machine Tool Spindle Center

Description

Product Overview A08-1501-05L Rotoflux Rotary Union

The A08-1501-05L Rotoflux Rotary Union is a precision-engineered rotary union designed for coolant delivery through the machine tool spindle center. It enables continuous and leak-free transfer of coolant from a stationary supply line into a rotating spindle, ensuring effective tool cooling, chip evacuation, and stable machining performance.

As a direct replacement for original Rotoflux rotary unions, the A08-1501-05L model offers identical mounting dimensions and comparable operating performance while providing a more cost-effective solution for CNC machine tool manufacturers and maintenance teams.

Designed for Through-Spindle Coolant Applications

The A08-1501-05L rotary union is specifically developed for through-spindle coolant systems, commonly used in modern CNC machining centers. By delivering coolant directly to the cutting zone, this rotary union helps:

• Improve cutting efficiency

• Extend tool life

• Enhance surface finish quality

• Reduce thermal deformation during high-speed machining

This makes it an essential component for high-performance milling, drilling, and tapping operations.

Key Features and Advantages

Stable Sealing at High Speed

The balanced sealing structure minimizes friction generated during rotation, allowing the rotary union to operate smoothly under continuous spindle rotation. This design reduces heat buildup and ensures long-term sealing stability.

Compact and Space-Saving Design

Machine tool spindles often offer limited installation space. The compact body design of the A08-1501-05L rotary union allows easy integration without modifying existing spindle structures.

Reduced Vibration and Wear

Internal spring-loaded components actively compensate for seal wear and help suppress turbulence and vibration caused by coolant flow, ensuring reliable operation under dynamic machining conditions.

Material Construction

• Housing: High-strength aluminum or brass (optional)

• Internal metal components: Stainless steel

• Seal system: Engineered for water-based coolant delivery

The combination of corrosion-resistant materials ensures excellent durability when operating with emulsions, cutting fluids, and water-based coolants commonly used in CNC machining environments.
