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 allowsan oil film to be formed between the balls and the ball raceway, thus improving lubricity andsignificantly extending the lubrication maintenance interval. Its structure consists of three major components: (1) a highly oil-impregnated fiber net (functions tostore 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

Wiper Ring “W” for the Ball Screw W
With Wiper Ring “W,” a special resin with high wear resistance elastically contacts the circumference of theball screw shaft and the screw thread, and eight slits remove foreign matter, thus preventing foreign matterfrom entering the ball screw nut.
● Features● A total of eight slits on the circumference remove foreign matter in succession, and prevent entrance of foreign matter.● Contacts the ball screw shaft to reduce the flowing out of grease.● Contacts the ball screw shaft at a constant pressure level using a spring, thus to minimize heat generation.● Since the material is highly resistant to wear and chemicals, its performance will not easily be deteriorated even if it is used
over a long period.
