Product Details

Formulated around thermosetting polymer resins, PTFE-based self-lubricating content, and high-strength fibers, this bearing material is designed to keep motion smooth while resisting wear, corrosion, and moisture-related swelling. During use, PTFE transfers to the mating surface and continually renews the lubricating film, helping maintain low friction through the service life. It is machinable for precision spherical parts and suits applications where load, temperature, and oscillation must stay under control.

Product Advantages

Self-Lubricating Film

PTFE transfers to the mating ball surface and continually renews a lubricating film, which helps keep friction stable over time.

Dimensionally Stable Under Load

The fiber-reinforced thermoset structure supports high load capacity with very low water absorption and low swelling.

Clean, Low-Noise Running

Low friction, non-conductive, and non-magnetic behavior make it a practical choice near electrical or sensor-sensitive assemblies.
