ROLLING BEARING WITH REDUCED FRICTION TORQUE

摘要

Rolling bearing comprising an inner ring (1), an outer ring (2), at least one row of rolling elements (3) between raceways (15a, 15b, 6) provided on the inner and outer rings (1, 2), and an annular housing (5) comprising at least one part (17, 18; 28) surrounding at least one of the rings (2), said outer ring (2) comprising two separate parts (2a, 2b), each of the two parts (2a, 2b) of said outer ring (2) defining one closed space (25a, 25b) with the housing (5). The ratio between the radius (R) of one raceway (15a, 15b) and the diameter (D) of the rolling elements (3) is higher than 0,55.
