Heavy-Duty Rod Seal
Series 190: Heavy-Duty Rod Seal
The 190 Series rod seal is a heavy-duty, low-friction design, consisting of a PTFE-filled seal and a profiled energizer. It is designed for large diameter and challenging applications, where high pressure and large extrusion gaps exist. The seal is ideal for short-stroke, dithering applications.
Installation
Benefits
Low friction
Short-stroke applications
High-temperature resistance
Low wear
Extrusion resistant
Compatible with a wide range of media
Available in diameters up to 2100 mm
Applications
The 190 Series heavy-duty rod seal is ideal for high-pressure sealing applications, offering low-friction performance and short-stroke capability.
Typical Applications
- Rolling Mills
- Injection Molding Machines
- Hydraulic Presses
- Forging Presses
The 190 Series is made from custom blended PTFE-filled compounds that provide ultra-low friction and high-speed performance with minimal wear. The standard compounds are PTFE with Bronze filler, or PTFE filled with Glass-Moly. The temperature range of the seal can be increased by selecting a FPM energizer in place of the standard NBR energizer.
