Abstract

The invention relates to a rolling bearing arrangement for lengthwise movement of a housing (2) on one or two mutually parallel rails (1, 40, 49) with torque transmission, in which one cylindrical outer surface sleeve section (4) is arranged in a common housing on each side of a longitudinal central plane (3) of the rail and the inside of each sleeve section (4) guides two or more rows of rolling bodies (8), whereby the envelope circle diameter (14) under the loaded rolling bodies (8) of the rows of each sleeve section (4) and the diameter (15) of the cylindrical outer surface (16) of the respective sleeve section (4) have a common center point (17) in cross section. In order to prepare this rolling bearing arrangement from a conventional full cylindrical rolling bearing in an economical type and manner and to ensure a shock-free rolling of the rolling bodies on and off, the common center (17) of a sleeve section (4) is arranged displaced opposite to the respective other sleeve section (4) at a distance transverse to the longitudinal center plane (3) of the rail (1, 40, 49). The individual sleeve sections (4) are produced by longitudinally slitting a conventional full cylinder slee…
