Request Product Information

The self-supported SX rotary joint provides a positive seal between stationary piping and a rotating cylinder and is applied to steam, water, and hot oil service. The SX incorporates two internal carbon-graphite bearings that permit self-alignment and long operating life – even on cylinders that are not concentric. Using new sealing technologies, the SX joint has extended seal life and increased reliability along with application flexibility.

The convex seal ring and optimized seal diameter provide extended seal life and reduced maintenance for the SX joint. The concept of applying different seal geometries to different media (steam, water, and oil) gives the SX joint a strong point of differentiation as well as a marked improvement in performance.

The SX rotary joint line is available in sizes from ¾” to 3” and can be used in single- or dual-flow applications. The joint is rated up to 343° C (650° F), 550 RPM, and 20 bar (300 psig).
