Green-Colored PTFE Guide Strip KXT PG120 — Wear-Resistant Bronze-Filled PTFE Bearing Strip for Hydraulic & Pneumatic Cylinders
Green-Colored PTFE Guide Strip KXT PG120 is a bronze-filled PTFE guide strip manufactured from PTFE compounded with 30–50% bronze powder and colored green for easy identification. The guide strip plays a guiding role inside hydraulic and pneumatic cylinders — it prevents the cylinder bore and piston rod from wear, resists chemical corrosion, absorbs vibration, and allows foreign particles to embed safely into the wear ring.
With the low friction of fluorocarbon resin (PTFE), excellent wear resistance, and good dry-running characteristics, KXT PG120 provides a higher load-bearing capacity, thermal-mechanical stability, and improved limit PV value compared to unfilled PTFE. Standard service range is -60°C to +150°C, tensile strength ≥ 15 MPa, and density 2.4–3.8 g/cm³ depending on bronze content.

Why Guide Strip
What is the role of a PTFE guide strip inside a cylinder?
Direct answer: A PTFE guide strip (also called a wear ring or bearing strip) is installed between the piston or rod and the cylinder bore to absorb side loads, prevent metal-to-metal contact, and guide the piston centrally inside the bore. Without a guide strip, the piston and rod rub directly against the cylinder wall, causing rapid wear and eventual seal failure. The guide strip also allows any foreign particles that enter the system to embed into the strip rather than scratch the cylinder bore or damage the primary seal.
Guides Piston and Rod
Maintains concentric positioning of the piston and rod inside the cylinder bore, preventing metallic contact and side-load damage.
Highly Wear-Resistant
Bronze filler gives the guide strip excellent wear resistance, even under sustained high load and elevated temperature.
Low Friction
PTFE provides the lowest coefficient of friction of any solid material — reducing heat build-up and improving cylinder efficiency.
Chemical Corrosion Resistance
PTFE is inert to virtually all industrial chemicals — suitable for hydraulic fluid, water-glycol, and aggressive media.
Absorbs Vibration
The guide strip damps vibration and shock loads, protecting both the cylinder wall and the primary seal.
Embeds Foreign Particles
Allows contaminant particles to embed into the strip itself, preventing scratches on the cylinder bore and seal damage.

Filled-Grade Comparison
How does bronze-filled PTFE compare with other guide strip materials?
Direct answer: Bronze-filled PTFE (KXT PG120) offers the highest compressive strength of the common PTFE guide strip materials — 15 MPa static at 25°C, dropping to 8 MPa at 120°C — with a maximum surface speed of 15.0 m/s. Carbon-filled PTFE can run dry at lower loads; phenolic (fabric composite) is used for heavy-load lubricated environments at lower surface speeds.
| Material | Compressive Strength | Max Surface Speed | Mating Surface | General Uses |
|---|---|---|---|---|
| Bronze-Filled PTFE (KXT PG120) |
15 MPa at 25°C 12 MPa at 80°C 8 MPa at 120°C |
15.0 m/s | Steel, hard chrome, hardened steel | Light load, lubricated environment |
| Carbon-Filled PTFE |
15 MPa at 25°C 12 MPa at 80°C 8 MPa at 120°C |
15.0 m/s | Stainless steel, hard anodised aluminium | Light duty, can run dry |
| Phenolic (Fabric Composite) |
300 MPa at 25°C (static) 50 MPa at 60°C (dynamic) |
1.0 m/s | Steel, hard chrome, hardened steel | Heavy load, lubricated environment |
Data per Kaxite datasheet. Choose bronze-filled PTFE for a balance of high speed and moderate load; choose phenolic composite for very heavy loads at low speed.
Applications
Where is the Green-Colored PTFE Guide Strip used?
Direct answer: KXT PG120 Green-Colored PTFE Guide Strip is used for piston and rod bearing applications in hydraulic cylinders, pneumatic cylinders, presses, and other linear motion equipment where side-load support, low friction, and long service life are critical.
Hydraulic Cylinders
Used as a wear ring on the piston and rod to guide the moving parts and protect the cylinder bore from metal-to-metal contact.
Pneumatic Cylinders
Provides guiding support in pneumatic actuators where low friction and dry-running capability are required.
Industrial Presses
Used in hydraulic presses and forming equipment to support the ram and prevent misalignment under high side loads.
Mobile Hydraulics
Construction, agricultural, and material-handling equipment where hydraulic cylinders operate under continuous load and vibration.
Linear Motion Equipment
Any cylinder or actuator where the piston must be guided centrally under side load — including marine, offshore, and industrial applications.
Chemical Processing
Used where the guide strip must also resist attack from hydraulic fluid, water-glycol, or process media — PTFE is virtually inert to all industrial chemicals.
