Compare all 5 grades and fillsHide
| Grade · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness |
|---|---|---|---|---|---|
PTFE-lubricated PEEK | Use where low friction is needed but the part must stay electrically insulating and non-abrasive to soft mating surfaces (aluminium, soft steel, food/medical contact variants). | 78 | 10 | 92 HRM | |
GL | Pick for vacuum, high-temperature or dry-gas service where PTFE outgassing or creep is unacceptable but a solid lubricant film is still required. | 95 | 4 | 98 HRM | |
ESD / conductive bearing grade | Choose for wafer-handling, fuel-system and explosive-atmosphere wear parts where static must be dissipated (surface resistivity 10^4–10^6 Ω) while running dry. | 105 | 110 | 2.5 | 86 Shore D |
FC30Default 10% carbon fibre / 10% PTFE / 10% graphite bearing compound | Standard injection-moulding bearing/wear compound; pick for dry-running bushings, seals and thrust washers needing the lowest friction and highest PV. | 130 | 2.5 | 100 HRM | |
30% carbon fibre reinforced wear grade | Pick when load capacity, creep resistance and stiffness dominate over lowest friction — e.g. high-PV bushings, back-up rings and structural wear pads. | 200 | 1.8 | 102 HRM |

What is PEEK-Bearing-Grade?
PEEK-Bearing-Grade (Ketron HPV, Victrex 450FC30) is an internally lubricated polyaryletherketone compounded with carbon fiber, PTFE and graphite to give a low coefficient of friction and high wear resistance without external lubrication. Engineers use it for dry or marginally lubricated running surfaces at 130 MPa tensile strength, 7.7 GPa modulus, 0.9 W/m·K thermal conductivity and 250 °C service; typical forms are extruded or compression-moulded rod, tube and plate plus injection-moulded parts. Elongation is 2.5%, and the PTFE-rich surface blocks welding and coating. Where stiffness and load dominate over friction, PEEK-CF30 is the alternative. PEEK-Bearing-Grade has a density of 1.44 g/cm³ (0.052 lb/in³), heavier than 85% of polymer grades. Its glass-transition temperature is 150°C (302 °F). PEEK-Bearing-Grade has a yield strength of 115 MPa (16.7 ksi) and a tensile strength of 130 MPa (18.9 ksi) — stronger than 99% of polymer grades. Elongation at break is 2.5% and the elastic modulus is 7.7 GPa (1.12 Msi).

Working with PEEK-Bearing-Grade
Is PEEK-Bearing-Grade easy to machine?
Machines cleanly but the carbon fibre and graphite are highly abrasive — use PCD or fine-grain carbide, sharp positive rake, high speed with light feed and air/mist cooling; stress-relieve at ~200 °C before finish cuts on thick sections.
Can PEEK-Bearing-Grade be welded?
Effectively non-weldable: the PTFE-rich surface prevents ultrasonic, hot-plate and laser fusion; join by threads, press fits, snaps or high-temperature adhesives after plasma/etch surface activation.
Can PEEK-Bearing-Grade be formed, bent or molded?
Injection mould at 370–390 °C melt with 180–200 °C mould and hot runners; dry 3 h at 150 °C, avoid sharp gates that break fibre, and expect anisotropic shrinkage (≈0.2% flow / 0.6% cross-flow).
PEEK-Bearing-Grade chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

What surface finishes work on PEEK-Bearing-Grade?
Ships as an opaque black self-lubricating part; no plating or paint adheres reliably — deburr and finish-turn to Ra 0.2–0.8 µm, and machine the counterface to Ra ≤0.4 µm to develop the transfer film.

PEEK-Bearing-Grade — frequently asked
What is PEEK-Bearing-Grade used for?
PEEK-Bearing-Grade is typically used for plain bearings, bushings, thrust washers, seal rings and compressor components. In short: self-lubricating PEEK compound; lowest friction in family; no external lubrication needed.
What is the yield strength of PEEK-Bearing-Grade?
PEEK-Bearing-Grade has a typical yield strength of 115 MPa (16.7 ksi) and a tensile strength of 130 MPa (18.9 ksi) — stronger than 99% of polymer grades. Strength varies by condition: see the 5 listed tempers.
Is PEEK-Bearing-Grade easy to machine?
Reasonably — machinability is rated good (55/100, worse than 64% of polymer grades). Machines cleanly but the carbon fibre and graphite are highly abrasive — use PCD or fine-grain carbide, sharp positive rake, high speed with light feed and air/mist cooling; stress-relieve at ~200 °C before finish cuts on thick sections.
Can PEEK-Bearing-Grade be welded?
Not readily — weldability is rated poor (20/100). Effectively non-weldable: the PTFE-rich surface prevents ultrasonic, hot-plate and laser fusion; join by threads, press fits, snaps or high-temperature adhesives after plasma/etch surface activation.
What surface finishes work on PEEK-Bearing-Grade?

What is the maximum service temperature of PEEK-Bearing-Grade?
PEEK-Bearing-Grade is rated for continuous use to about 250°C (482 °F), and briefly to 310°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between PEEK-Bearing-Grade FC30 and PEEK-Bearing-Grade ESD?
FC30 is the default condition — standard injection-moulding bearing/wear compound; pick for dry-running bushings, seals and thrust washers needing the lowest friction and highest PV. ESD: choose for wafer-handling, fuel-system and explosive-atmosphere wear parts where static must be dissipated (surface resistivity 10^4–10^6 Ω) while running dry. Yield strength is 115 MPa in FC30 versus 105 MPa in ESD.
How much does PEEK-Bearing-Grade cost?
