How to use this SKF bearing catalogue


SKF rolling bearing catalogue is divided into two main sections: a technical section and a product section. The technical section describes how to select and apply SKF rolling bearings and covers eight main topics marked with printed tabs from A to H. The product section is divided into chapters by product type. Each chapter contains specific information about the SKF bearing type and its optional variants and product tables. Each product chapter is marked by cut tabs with an easily identifiable icon.

A quick way to access detailed product data is via a product table number or SKF bearing size chart. Product table numbers are listed at the front of the product catalogue, at the beginning of each product chapter, and in the product index at the back of the catalogue.

SKF Rolling bearings catalogue

This catalogue contains the standard assortment of SKF rolling bearings typically used in industrial applications. To provide the highest 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 earlier catalogues because of redesign, technological developments, or revised calculation methods. SKF reserves the right to continually improve its products concerning materials, design, and manufacturing methods driven by technological developments.

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 fulfil additional 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 tech­medical 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, fric­on, general design considerations and lubri­cation is discussed in detail. Installation and maintenance information is also included. More practical information about mounting and maintenance is provided in the SKF bearing maintenance handbook (ISBN 978­91­978966­4­1).
