The unit (1) has inner rings (5, 6) arranged on a shaft (2), and two rows of roller bodies arranged among the inner rings and an outer ring (4). Each row of the roller body is arranged in an axial region (12) of the inner rings, where the axial region is raised from the shaft. Each inner ring exhibits axial ranges (13, 14) that are held on the shaft in press-fit manner. The roller bodies are formed in an O-arrangement. The axial region extends to front side (15) of the inner rings.
