Linear ball bearing and supporting race element for the same

A linear ball bearing for a longitudinally movable mounting of a shaft-like guide rail in a part which surrounds the guide rail, comprising:

• a sleeve-like cage having recesses arranged one behind the other in a circumferential direction holding ball circuits, each ball circuit having at least one supporting section with supporting balls which are supported such that the supporting balls roll on the guide rail, the supporting balls of each ball circuit are supported such that the supporting balls roll on a raceway of a supporting race element, which is inserted indirectly or directly into the cage, the supporting race element has at least one radial outer surface for contact against an inner surface of the part which surrounds the guide rail,
• wherein the at least one radial outer surface is formed by at least one web-like projection which extends in the longitudinal direction of the supporting race element,
• wherein the supporting race element is produced from a blank as a drawn profile, which has the at least one web-like projection, and
• wherein the at least one web-like projection is embossed such that the at least one web-like projection is provided at least in the longitudinal direction with an outwardly arched outer surface.
