These materiais consist of metal backing bonded to a porous bronze sintered layer with PTFE based polymer bearing layer.The metal backing provides mechanical strength, while the bronze sinter layer provides a strong mechanical bonding between the backing and the bearing lining,the PTFE based polymer offers exceptional low friction even under dry condition and the thermoplastic based polymer is generally designed to operate with marginal lubrication.
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.
