Zusammenfassung:	To provide novel bearing and seal assemblies exhibiting both improved wear resistance and an improved coefficient of friction.SOLUTION: A layer 30 disposed on a substrate 20 of a bearing assembly includes a polyimide matrix and a filler dispersed within the polyimide matrix. The filler can be a thermoplastic polymer, such as PTFE, and/or an organic filler.SELECTED DRAWING: Figure 1 【課題】改善された耐摩耗性及び改善された摩擦係数の双方を示す新規のベアリング及びシールのアセンブリを提供する。【解決手段】ベアリングアセンブリの基材２０上に被着される層３０は、ポリイミドマトリックス及びポリイミドマトリックス中に分散された充填剤を含む。充填剤は、ＰＴＦＥといった熱可塑性ポリマー及び／又は有機充填剤であり得る。【選択図】図１
