Abstract
A roller cage for a longitudinal guiding device, mounted on rolling bearings, is provided with apertures in which rollers are inserted. The apertures have a substantially rectangular cross-section, which is formed by four side faces, and are machined down. On the inside edge region of each aperture, collar-shaped projections are provided which protrude out of the side faces. The outside edge region of the aperture is plastically deformed by pressing in, so that a protruding edge is formed. By means of the collar-shaped projections and the protruding edges the roller is held in the aperture, the collar-shaped projections and the protruding edges being designed such that they do not come into contact with the support region of the roller. The friction of the roller is thereby less; the life increases.
