SX Rotary Joints

SX Rotary Joints
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 rotary joint 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 rotary joint has extended seal life and increased reliability along with application flexibility.

The SX rotary joint line is available in sizes from 3/4” to 3” and can be used in single- or dual-flow applications. The joint is rated up to 650°F (343°C), 300 psig (20 bar), and 550 rpm.
