A linear ball-bearing device for guiding an object along a cylindrical shaft including comprising a bearing block having a contact surface for contacting the object and having a plurality of ball loops, each ball loop comprising radially inner and radially outer ball rows interconnected by curved ball deflection rows, the radially inner ball rows being supported radially outwardly on axially extending load-carrying surfaces which are provided on a cylindrical inner surface of the bearing block, the radially outer ball rows running in return channels in the bearing block and the deflection-curve ball rows being guided by concave semi-circular grooves which are arranged on a cage sub-assembly, the cage sub-assembly having hook flanges each of which has an axially inwardly directed hook end surface engaging an axially outwardly directed channel aperture surface of the respective return chamber, each hook flange also having an outer peripheral surface for engagement with an inner peripheral surface of the bearing block, the load-carrying surfaces, the return channels, the inner peripheral surfaces and the channel aperture surfaces being integrally formed on the material of the bearing block.
