Rolling bearing for longitudinal movements

摘要

A rolling bearing for longitudinal movements has a cage sleeve which can be installed in a cylindrical bore (3) of a housing (2) and has endless rows of rolling elements distributed over its circumference. Installed in the cage sleeve are track rails (29) for in each case at least one row of rolling elements and these track rails can be supported in the bore (3) of the housing (2). Each track rail (29) is provided on its radially outward-facing and radially inward-facing side (10, 16) with a curvature extending in the circumferential direction. To allow rolling bearings with different outside diameters to be produced economically, each track rail (29) has a curvature with a large radius (R) of curvature corresponding to the larger outside diameter on one side and a curvature with a small radius (r) of curvature corresponding to the smaller outside diameter on its other side (16). <IMAGE>
