Overview
The DN40 universal rotary union is a low speed single-passage rotating joint designed for reliable fluid transfer between stationary supply lines and rotating equipment. With a 40mm inner diameter (1.5 inch nominal bore) it delivers high flow capacity while maintaining a compact footprint. The self-aligning design with 20° floating angle automatically compensates for minor misalignment, reducing shaft stress and extending seal service life. Applicable media include water, compressed air and saturated steam. Advantages include low maintenance, leak-proof operation and cost-effectiveness.

Core Advantages

• Self Aligning 20 Degree Floating Design — Rotor freely adjusts within a 20° floating range to compensate installation misalignment, minimizing vibration and mechanical stress on bearings and seals.
• Stable Low Speed Performance — Engineered for applications up to 10 RPM, ensures smooth, leak-free operation in low speed rotating tables, rollers, turntables and indexing machinery.
• High Pressure and Temperature Capability — Rated for working pressures up to 1.0 MPa and temperatures up to 200 °C; sealing system remains stable under continuous saturated steam service.
• Multi Media Compatibility — Single universal model handles water, compressed air and saturated steam, simplifying inventory and reducing procurement cost.
• Low Maintenance and Leak Proof — Optimized seal structure provides long-term leak-free performance; self-aligning reduces seal wear and extends maintenance intervals.
• Cost Effective Solution — Universal design offers cost savings compared to dedicated rotary joint configurations.
