  • Patent number: 8695197
    Abstract: A method for producing a coated pull-out guide for baking ovens, the pull-out guide including a guide rail and at least one of a middle rail and a running rail displaceably supported by rolling elements on the guide rail. The rolling elements are guided along tracks on one or more of the guide rail, middle rail and running rail. The method includes the steps of: assembling the pull-out into a unit including one or more of the guide rail, middle rail, and running rail; cleaning a metal surface of at least one of the rails by one or more of a mechanical and chemical cleaning method; and, applying a coating to the cleaned metal surface.

  • Publication number: 20110262768
    Abstract: A method for producing a component of a pullout guide for high-temperature applications includes the method steps of: producing a metal blank; applying a plasma polymer coating to a surface of the blank; heating the coated blank to a temperature of at least 400° C.; and cooling the coated blank, thereby producing the component. A metal component is produced by the method. The component is used in combination with household appliances.

  • Publication number: 20110187253
    Abstract: The invention relates to a fitting, for example a drawer slide for household appliances, comprising two rails that can move relative to one another and that are slid toward one another by way of rolling elements. In the process, the tracks (6, 8) of the rolling element (4) are lubricated at the rails (2, 3) at least in areas by way of a lubricant (7) comprising a boronitride and/or polysiloxane. This facilitates an efficient use of lubricant (7), which is also stable at high temperatures. The invention further relates to a lubricant, in particular for fittings in household appliances, that is stable at temperatures of over 600° C. and can be used in wet and humid areas.
