Analýza tribologických vlastností kompozitného materiálu PA66+GF25

The aim of experiments was to acquire the knowledge that can be used in designing materials for bearing cages. The current trend is that leading bearing manufacturers are replacing metal cages in bearing construction with glass fiber (GF) reinforced polyamide (PA) cages. Experimental measurements were realized on the experimental device linear microtribometer working on the principle of method ball on plane. This method according to the standard ISO 7148-2 is standard method for tribological properties testing. The structure analysis of experimental samples was performed because of understanding of potential structure influence on material properties.
