Material: Pure PTFE or reinforced with inorganic fillers such as glass fiber, graphite, copper powder, and molybdenum disulfide. Phenolic laminated or POM wear-resistant materials are also available.

Technical Specifications:

• Pressure: 0–30 MPa

• Temperature: -200～260 ℃

• Chemical Compatibility: pH 0–14; resistant to most strong acids, strong alkalis, organic solvents, hydraulic fluids, and emulsions.

Key Features: Extremely low friction coefficient with superior self-lubrication ensures smooth motion without stick-slip and minimal noise. Highly wear-resistant, extrusion-resistant, and capable of withstanding high compressive loads; absorbs radial misalignment and lateral loads to prevent direct metal-to-metal contact between the piston rod and cylinder bore, avoiding scoring. Resistant to creep, operates reliably across wide temperature ranges, and offers excellent corrosion resistance without attacking mating metal components. Easy to install, effectively protects the cylinder barrel and piston rod, and extends seal service life.

Application areas: reciprocating motion guidance and support for chemical hydraulic cylinders, heavy-duty metallurgical hydraulic cylinders, construction machinery cylinders, injection molding machines, pump and valve equipment, power generation hydraulic systems, food and pharmaceutical hydraulic devices, and more.
