Non-metallic self-lubricating bearing include the environmentally friendly, lead- free polymer bearing material consists of PTFE (polytetrafluoroethylene), PPS (polyphenylenesulfide), PEEK (Polyetheretherketone), Nylon (polyamide) with a special filler. They are suitable for the dry lubrication applications. POLYMER BEARINGS are made by injection with high performance engineering plastic mixed with proper intensifier and lubricants which could significantly improve the bearing load capacity and impact resistance of the bearing. Included lubricants can reduce the friction factor considerably.

To use the word "Dung" (Impartiality) to raise the Name is to shine the light on truth, to use the word "Luan" (Interpretation) to call the Name, is to understand the words. If the truth is not Named, it cannot enlighten, and so it is bound to "Dung" in order to be portrayed. Words, when unexplained, cannot be understood, so we must utilize "Luan" in order to to illustrate. When the truth has been portrayed, the words has been illustrated, then the practice and introspection can be left hanging. That is clear.
