CATALOG No.322-1E Options for the Ball Screw QZ Lubricator Wiper Ring “W” QZ Lubricator for the Ball Screw Wiper Ring “W” 1 Wiper Ring “W” QZ Lubricator OPTIONS For Ball Screws, dust-prevention and lubrication accessories are available. You can make a selection according to the application or mounting location. 2 QZ Lubricator for the Ball Screw QZ The QZ Lubricator feeds a right amount of lubricant to the ball raceway of the ball screw shaft. This allows an oil film to be formed between the balls and the ball raceway, thus improving lubricity and significantly extending the lubrication maintenance interval. Its structure consists of three major components: (1) a highly oil-impregnated fiber net (functions to store a lubricant), (2) a high-density fiber net (to apply the lubricant to the raceway) and (3) an oil control plate (to control the flow of the lubricant). The lubricant contained in QZ Lubricator is fed to the ball screw shaft, based on the principle of capillary action, which is used in felt-tip pens and other products. ● Features ● Since it supplements an oil loss, the lubrication maintenance interval can significantly be extended. ● Since the right amount of lubricant is applied to the ball raceway, an environmentally friendly lubrication system that does not contaminate the surroundings is achieved Flow of lubricant ( 3 ) Oil control plate ( 2 ) High-density fiber net ( 1 ) Highly oil-impregnated fiber net Applied directly to the raceway Ball screw shaft Sealed case Ball screw nut QZ Lubricator QZ Lubricator QZ fixing screw Ball screw shaft Ball Ball screw nut Air vent (see note) Appearance Drawing Structural Drawing 2 QZ Lubricator has an air vent. Do not block the vent with grease or the like. Note Performance ■ Significantly extended maintenance interval Since the QZ Lubricator continuously feeds lubricant over a long period, the maintenance interval can significantly be extended.
