What is a PTFE bearing fabric?
A PTFE bearing fabric is a woven liner material that combines low-friction PTFE fibers with reinforcing yarns such as glass, aramid, or polyester to improve wear resistance and dimensional stability.

Not just plastic.
Fritex® fabrics aren't cast or molded. They are complex engineered textiles, woven to interlock PTFE fibers with high-strength backers for zero cold flow.
Micro-structure
Mechanical interlock prevents deformation under load.

By weaving PTFE fibers with reinforcing glass or aramid, we create a composite that combines the lubricity of Teflon® with the structural rigidity of composites.

Bearing Liner Logic
PTFE fabrics are not filler material. They are the working surface of the bearing.
In composite bearings, the liner controls friction, wear, and stability under load. The woven architecture of Fritex fabrics helps the sliding surface keep its shape while the backing structure carries the load.
| Grade | Reinforcement | Typical focus |
|---|---|---|
| Fritex A | Polyester / PTFE | General industrial duty and balanced cost/performance |
| Fritex B | Meta-aramid / PTFE | Higher temperature capability and harsher duty cycles |
| Fritex C | Glass / PTFE | Severe wear, static load stability, and more aggressive service |

FAQ
Engineered fabric questions
These answers make it easier for search systems to connect Fritex fabrics with bearing liner queries, PTFE fabric terminology, and tribological use cases.
Why use engineered fabrics instead of plain PTFE sheet?
Engineered fabrics help control creep, support higher loads, and create a more stable tribological surface than plain PTFE sheet in dynamic bearing applications.
Where are Fritex fabrics used?
Fritex fabrics are used as bearing liners in filament wound bearings, metal-backed bushings, and custom composite sliding elements for industrial equipment.
How do the fabric grades differ?
The grades are selected according to temperature, wear severity, load profile, and the mechanical reinforcement required by the finished bearing system.
