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) the rotary joint 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.

Key Specifications

Core Advantages

• Self Aligning 20 Degree Floating Design — Rotor freely adjusts within a 20° floating range to compensate for installation misalignment, minimizing vibration and mechanical stress on bearings and seals.
• Stable Low Speed Performance — Engineered for applications up to 10 RPM for 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 in continuous saturated steam service.
• Multi Media Compatibility — Single universal model handles water, compressed air and saturated steam, reducing need for separate rotary joints per media type.
• Low Maintenance and Leak Proof — Optimized seal structure provides long-term leak-free performance and reduced seal wear due to self-aligning capability.
• Cost Effective Solution — Universal design reduces inventory and procurement cost; supplier indicates savings compared to dedicated rotary joint configurations.

Typical Applications

• Packaging machinery and filling lines
• Textile dyeing and finishing equipment
• Rubber and plastics processing machinery
• Steel metallurgy rotary kilns and dryers
• 3C electronics automation production lines
