PTX™ Rotary Joints
PTX™ Rotary Joints (US Patent No. 5,098,135)
The PTX rotary joint and stationary syphon system incorporate the latest developments in seal design and drying technology for paper dryers. The lightweight design makes for easy installation; yet its heavy-duty construction handles high pressure, high speed, and angular misalignment. The PTX can also accommodate thermal expansion of the dryer journal – even when used on the front side of paper machines.
The patented PTX steam joint design uses a spring-loaded piston that applies balanced pressure on the seal ring to keep it securely seated against the wear plate. The wear plate is attached to the journal or a filler flange. The wear plate rotates while the piston remains stationary. The seal ring is free floating to accommodate angular and offset misalignment.
With its spring-loaded piston and reverse seal, the PTX seal technology is a far different design than conventional seal packages. These advanced design differences make the PTX a more reliable, easier-to-maintain joint - even under the most difficult operating conditions. The PTX is rated up to 400° F (205° C), 160 psig (11 bar), and 500 RPM (8,000 fpm).

LN™ Rotary Joints
The LN rotary joint is designed for steam service and is commonly applied to paper dryers, synthetic fiber rolls, food processing dryers, and other installations where external framework is available for support. Using two external rods for support, the LN is available in either single- or dual-flow applications with a rotating syphon pipe. Sizes range from 1/2” to 8” and the steam joint is rated up to 650° F (343° C), 510 psig (35 bar), and 200 RPM.

ELS™ Rotary Joints
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 1.25” up to 10” and the joint is rated up to 650° F (343° C), 310 psig (20 bar) and 200 RPM.
