Fluid Rotary Union
Rotary unions that carry water, coolant, oil, grease, air and special gases between rotating and stationary parts — 2 to 20+ passages, up to 35 MPa.
0–35 MPa
Rated pressure
2–20+
Passages
≤ 200 rpm
Rated speed
≤ 20 M
Revolutions service life
Overview
Fluid through the axis, sealed for the duty.
Precision sealing structures give long service life and stable performance under high pressure. Electrical and fiber-optic channels can be integrated in the same assembly.
Design advantages
- Mechanical, clearance or hybrid seals chosen for the medium and pressure
- Multiple independent passages in one housing
- Integrates with electrical and fiber-optic channels
- Threaded or flanged interfaces; aluminum or stainless housing
