Key Features of Rotoflux s-serien Rotary Union
Durable Housing Made from Brass or Aluminum with Stainless Steel Components
RotoFlux engineers the S-Serie rotary union with a high-strength housing made from either brass or lightweight aluminum to ensure long-term durability and corrosion resistance. They use premium-grade stainless steel for all other metallic parts, including the shaft and sealing elements, to deliver excellent wear resistance and reliable performance in demanding environments.
Integrated Spring Mechanism for Vibration and Turbulence Control
To ensure stable and consistent operation, a precision-calibrated internal spring is incorporated to absorb vibrations and reduce fluid-induced turbulence. This helps to maintain smooth rotation even at high speeds or under fluctuating pressure conditions, extending the lifespan of internal components.
Low-Friction Balanced Seal with Micro-Fit Overlap Design
The rotary union features a finely machined micro-overlap seal structure and a dynamically balanced sealing ring. This design minimizes contact friction during rotation, significantly reducing heat generation and power loss. It’s ideal for high-speed applications that demand efficiency and low maintenance.
Oil-Soaked Felt Seal for Reliable Vacuum and Air Operation
When operating in air or vacuum environments, the S-Serie employs a sealed felt ring saturated with lubricant. This smart design ensures consistent sealing performance while maintaining minimal resistance, making it suitable for pneumatic systems or vacuum applications where traditional seals may fail.
You can pass air through the unit at a pressure of 10 kg and a speed of 4000 rpm; the system classifies it as either N-type or D-type.
You can also pass vacuum at a pressure of 6.7 kg and the same speed of 4000 rpm, with options available in both N-type and D-type configurations.
For hydraulic oil, the unit handles a pressure of 50 kg at 4000 rpm and is also available in N-type and D-type variants.
RotoFlux equips the system with a graphite seal (standard seal) for vacuum and air cooling applications.
For hydraulic oil cooling, RotoFlux uses a D-type tungsten carbide seal designed specifically for heavy-load conditions.
