An inner-ring-fastened roller sleeve includes an inner ring and a roller-and-cage assembly. The inner ring is arranged for fastening on a shaft or axle and includes an outer lateral surface with an inner raceway, and first and second flanges extending radially outwards. The second flange includes a larger outer diameter than the first flange and an edge region bent axially towards the first flange. The roller-and-cage assembly is disposed on the inner ring and guided by the first flange and the second flange. The roller-and-cage assembly includes a bearing cage formed as an axially slotted plastic cage and a plurality of roller-type rolling elements inserted into the bearing cage and arranged to roll on the inner raceway. The bearing cage includes a first side ring radially surrounded by the edge region to fix the roller-and-cage assembly in the inner ring, a second side ring, and a plurality of connecting webs.
