Foreword

This catalogue contains the standard assort ment of SKF rolling bearings typically used in industrial applications. To provide the highest levels of quality and customer service, these products are available worldwide through SKF sales channels. For information about lead times and deliveries, contact your local SKF representative or SKF Authorized Distributor.The data in this catalogue reflect SKF’s state-of-the-art technology and production capabilities as of 2012. The data contained within may differ from that shown in earlier catalogues because of redesign, technological

developments, or revised calculation methods.SKF reserves the right to continually improve its products with respect to materials, design and manufacturing methods, some of which are driven by technological developments.Getting started This catalogue contains detailed information about standard SKF rolling bearings, several special engineered products and bearing accessories. Engineered products include motor encoder units, which can measure the speed and direction of rotation, polymer bearings and rolling bearings designed to fulfiladd itional requirements, such as:

• extreme temperatures
• electrical insulation
• dry lubrication
• insufficient lubrication
• rapid speed changes
• high vibration levels
• oscillating movements

The first section, which contains general technical information, is designed to help the reader select the best, most effective products for a particular application. In this section,bearing service life, speed capabilities, friction, general design considerations and lubrication are discussed in detail.
