Water rotary union

for airfor oilfor vacuum

Product description

Rotary unions (rotary joints) are mechanical components that enable transfer between stationary and rotating machine parts. They include: couplings for shaft power transmission, rotary unions for fluid/gas transfer, slip ring assemblies for electrical power/signals, and waveguide rotary joints for microwave transmission.

Design and sealing options

Available with two balanced, microlapped sealing assemblies:

• O Seal (standard): carbon-graphite to carbide sealing — recommended for filtered water.
• N Seal (heavy-duty): carbide-to-carbide sealing — for poorly filtered or abrasive fluids.

Fluid pressure above 8 bar is permitted only with cool water up to 125°F (50°C). Do not operate continuously at maximum application limits; verify compatibility of media and operating conditions before use.

Applications and media

Used across many industrial sectors where media must pass between fixed and rotating parts.

• Typical media: water, oil, grease, emulsions, compressed air, gases, vacuum.
• Common applications: machining centers, rotating drums, spindles, industrial cooling, hydraulic/pneumatic systems, process equipment.

Key benefits for buyers

• Simplified integration: compatible with combined hydraulic, pneumatic and electrical systems.
• Reduced downtime: sealing options for varied media reduce maintenance frequency.
• Versatility: interchangeable sealing configurations for different process requirements.
