Inner-ring-fastened roller sleeve and method for producing same

An inner-ring-fastened roller sleeve, comprising:

• an inner ring arranged for fastening on a shaft or axle, the inner ring formed as a one-piece component,
• a roller-and-cage assembly disposed on the inner ring, the roller-and-cage assembly comprising:
• a bearing cage formed as an axially slotted plastic cage, the bearing cage comprising:
• two side rings,
• a plurality of connecting webs, and
• a plurality of rolling elements inserted into the bearing cage, the rolling elements:
• i) retained by the bearing cage at regular spacings in a circumferential direction, and ii) roll on an inner raceway formed by an outer lateral surface of the inner ring, and
• the roller-and-cage assembly is axially guided via two flanges provided on opposite axial sides of the inner ring and extending radially outwards, and a first one of the two flanges has a larger outer diameter than a second one of the two flanges and, the first one of the two flanges is configured with an edge region bent axially towards the plurality of rolling elements, and
• one of the two side rings of the bearing cage is radially surrounded by the edge region so as to fix the roller-and-cage assembly in the inner ring.
