Abstract

An apparatus for shaping plastics material pre-forms into containers has a plurality of blow molding stations arranged on a movable carrier The blow molding stations have two part blow molds with a cavity inside in which the plastics material pre-forms are expanded. The blow molding stations have stressing devices which act upon the plastics material pre-forms to expand them with a flowable medium. At least one first bearing device is provided for movable mounting of the blow mold carriers with respect to each other and at least one second bearing device is provided for movable mounting of the first locking element with respect to the second locking element. At least one of these bearing devices is a slide bearing without lubricant or a bearing which is injection molded at least in part from a plastics material between bearing parts movable relative to each other.
