The widest range of polymer ball bearing applications is covered by xirodur® B180. However, if the color "white" does not suit your application, for example if the bearing is designed as a visible part, the material xirodur® S180 is the right one. This material offers almost identical technical properties to xirodur® B180, but is not quite as wear-resistant. Its characteristic feature is its black color, which also offers greater UV resistance than xirodur® B180. This also makes it perfect for outdoor use.
