An injection molding tool for producing a cage for a linear bearing in which several rolling elements are positioned in the cage in the direction of its longitudinal extent in the assembled state includes two tool halves each provided with protrusions. The protrusions extend into the cavity of the tool during the injection molding process and form a portion of a receiver pocket for receiving a rolling element. To make the injection molding process simple and economical, the protrusions are fixedly connected with the tool halves, with the protrusions being are shaped in such a way that, when acting together, they form holding elements for retaining the rolling elements in the receiver pockets in the cage when the injection molding tool is closed. The holding elements are thus integrated into the basic geometry of the cage. A rolling bearing cage for a linear bearing is provided with a plurality of receiver pockets for holding rolling elements next to each other in a manner arranged along the longitudinal extent of the bearing. The cage is also provided with holding elements integrated into the basic geometry of the cage for retaining the rolling elements within the receiving pockets.
