    Abstract: A bearing assembly (10; 100) suitable for use as a journal bearing for a high-pressure fuel pump is disclosed. The bearing assembly comprises a generally tubular bearing bush (20; 200) made entirely from a PEEK-based material, and defining an inner bearing surface (22; 222), and a housing (40; 400) comprising a generally cylindrical bore (42; 442) for receiving the bush (20; 200). The bush (20; 200) and the housing (40; 400) are arranged concentrically around a bearing axis (A). The housing (40; 400) includes cooling means (54, 56, 58; 454) for cooling the bearing assembly (10; 100), in use.
