When it comes to fitting rolling bearings, even small errors can have serious and costly consequences. The Schaeffler Mounting Toolbox is a web-based information source on how to professionally install rolling bearings. Users can learn about what tools and fitting aids are needed, and short video sequences are provided to demonstrate how these are used. A virtual factory hall serves as an interface and allows interactive navigation. The toolbox provides details of tools and accessories, and demonstrates the advantages of properly mounted rolling bearings as well as correct aligning and lubrication. The topics are displayed in the form of pillars, drawers, and machines, so everything is structured clearly. There are three main topics in the virtual factory hall: mounting/dismounting, aligning, and lubrication. The subtopics contain the tools and fitting aids that are shown in the videos. The user is also given an insight into the different mounting methods, as well as general safety guidelines and preparations. The experts show how the bearings are fitted and dismantled in short film sequences. The Mounting Toolbox is currently available in German, English and Russian. Spanish, Portuguese, French, and Chinese versions are in progress and will be put online once completed.
