Heavy-Duty Piston Seal
Series 288: Heavy-Duty Piston Seal
The 288 Series Heavy-Duty Piston Seal is a low-friction design, consisting of a PTFE filled seal, a profiled energizer and two integrated backup rings. It is designed for large-diameter, double-acting cylinders in challenging applications, where high pressure and large extrusion gaps exist.
Installation
Benefits
Low friction
Double acting applications
High-temperature resistance
Low wear
Compatible with a wide range of media
Available in diameters up to 2100 mm
Applications
The 288 Series heavy-duty piston seal is ideal for high-pressure sealing applications, offering low-friction performance and double-acting operation.
Typical Applications
- Forging Presses
- Extrusion presses
- Stamping presses
- Rolling Mills
- Injection Molding Machines
- Hydraulic Presses
The 288 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 filled with Bronze filler, or PTFE filled with Glass-Moly. The backup rings can be made from Polyamide, Delrin and POM. The temperature range of the seal can be increased by selecting a FPM energizer in place of the standard NBR energizer.
