8 Plant asset efficiency maintenance programmes, and the industry s most advanced supply management techniques. The SKF brand still stands for the very best in rolling bearings , but it now stands for much the knowledge engineering company4 ForewordMany applications require bearings that are suitable for oscillating movements and that can accommodate misalignment. Rolling bearings only partly fulfil these requirements as they are generally designed for continuous rotation and can only accommodate limited , SKF manufactures spherical plain bearings and rod ends to provide an economical solution to these challenges.

9 This catalogue presents the current assort-ment of SKF spherical plain bearings and rod ends. Structure of the catalogueThe catalogue starts with general product infor-mation, followed by nine main chapters, which are marked with numbered blue tabs in the right margin:Chapter 1 provides design and application 2 to 7 describe the various bearing and rod end types. Each chapter contains descriptions of the products as well as prod-uct tables, listing data for selecting a bearing or rod end and designing the bearing 8 is an overview about other SKF products and chapter 9, all products presented in this catalogue are listed in alphabetical order by designation.

10 About the data in this catalogueThe data in this catalogue relate to SKF s state-of-the-art technology and production capabil-ities as of beginning 2010. The data may differ from that shown in earlier catalogues because of revised methods of calculation, redesign or technological developments. For example, the following new information and product data have been included for radial spherical plain bearings : bearings in the TX series have been added and are available with bore diameters up to 800 in the maintenance-free series are fitted with LS seals as standard.
