The ELS (Extended Life Series) rotary joint is a self-supported joint that has been specifically designed to solve accelerated wear problems that occur with conventional self-supported rotary joints – particularly those in high vibration applications. The double-guide design provides internal support for the joint and maintains alignment even when the roll or cylinder is not concentric. The ELS is available in single-flow or with stationary syphon dual-flow configurations for steam service. Sizes range from 2" up to 12" and the joint is rated up to 650° F (343° C), 300 psig (20 bar) and 200 RPM.
