Guide rail with a cover strip for a linear bearing

A guide rail for a linear bearing, comprising a guide rail with a longitudinal groove which is arranged along the guide rail on the upper rail side thereof, with a cover strip which closes the longitudinal groove to the outside and bears flush against the plane of the upper rail side, wherein a clear spacing between opposite groove walls of the longitudinal groove is smaller than the extent of the cover strip, which is to be fitted, transversely with respect to the longitudinal groove, and wherein, in order to secure the cover strip on the guide rail, the groove walls are each provided with an undercut, and wherein retaining strips which are provided on both longitudinal sides of the cover strip engage in the undercuts, wherein in order to insert the cover strip into the longitudinal groove, the cover strip is plastically curved about an axis which is parallel to the guide rail such that the extent of said cover strip transversely with respect to the longitudinal groove is smaller than the clear spacing between the groove walls, the concave side of the curved cover strip facing the longitudinal groove, and, after being inserted into the longitudinal groove, the curved cover strip being leveled by means of plastic deformation such that the retaining strips are displaced into the undercuts.
