Foreword This catalogue contains detailed information on SKF rolling bearings that are typically used in industrial applications. It also includes information on engineered products such as: • • • • motor encoder units, which measure rotation speed and direction rolling bearings designed to withstand extreme temperatures bearings with electrical insulation bearings with balls or rollers made from ceramic materials Products presented in this catalogue are available worldwide through SKF sales channels. For information about lead times and deliveries, contact your local SKF representative or...

What is new in this edition The four main differences in this edition of the SKF catalogue Rolling bearings, compared to the previous, are described below. 1. The bearing selection process When selecting bearings for any purpose, ultimately you want to be certain of achieving the required level of equipment performance – and at the lowest possible cost. In addition to the bearing rating life, there are other key factors you must consider when putting together the bearing specifications for an application. The bearing selection process helps to evaluate these key factors. 3. Streamlined...

4. Important product updates Tapered roller bearings Tapered roller bearings with an outside diameter up to 600 mm have been redesigned. These new bearings have an increased dynamic load rating, and most of the range is available as SKF Explorer bearings. A consolidated catalogue assortment and a simplified designation system provide a clear view of what is available. Angular contact ball bearings with 25° contact angle These new bearings have a raceway geometry optimized for high speeds and reduced sensitivity to axial loading and misalignment. They can increase robustness when used as the...

Catalogue information and how to use it This catalogue is divided into three parts: Principles of rolling bearing selection This part is marked by grey bars at the page edge. It provides general information about rolling bearings (section A), explains the bearing selection process (section B), and presents three examples on how to apply the bearing selection process for various applications (section C). Grey bars mark the three sections under Principles of rolling bearing selection. Product data The part is divided into sections per bearing type. Each product section is marked by blue tabs...

Use case: Select a bearing for an application If you are unsure whether you have adequate knowledge or experience to select a bearing that best suits your application requirements, you will probably find the Bearing selection process, page 60, helpful. If you are an experienced bearing expert, go directly to the section for the relevant bearing type, browse the product tables for the required size, and then look at additional details and information on more specific variants in the text part preceding the product tables. This catalogue is for global use. Therefore, the predominant units of...
