What are PTFE bushings?
PTFE bushings are low-friction bearing sleeves made from PTFE (polytetrafluoroethylene). They are used to guide rotating or sliding components while reducing wear, stick-slip and noise. PTFE bushings are commonly applied where lubrication is limited or where chemical resistance is required.
Applications of PTFE bushings
PTFE bushings are used in mechanical assemblies, industrial equipment and sliding mechanisms. Typical applications include pivot points, guide systems, shafts and housings where a stable, low-friction interface is needed.
Key properties of PTFE bushings
- Very low coefficient of friction
- Good wear behaviour in sliding applications
- Chemical resistance to many media
- Suitable for a wide temperature range
- Non-stick surface characteristics
PTFE bushing types and designs
PTFE bushings can be supplied in different designs depending on the installation and load requirements, such as plain sleeves, flanged bushings or split bushings. Dimensions are typically defined by inner diameter, outer diameter and length.
PTFE bushings and material options
Depending on load and wear requirements, bushings can be produced from virgin PTFE or from filled PTFE compounds. Material selection depends on factors such as mechanical load, running conditions and the media the bushing is exposed to.
