5 In the last edi-tion SKF introduced the New Life Theory ,which since has become a major new tech-nical standard for the bearing industry. Withthis broad usage and professional accep-tance, the SKF General Catalogue is General -ly considered to be the authoritative refer-ence source of its type throughout General Catalogue was subsequentlyconverted to electronic formats for addedaccessibility and convenience available ina CD-ROM version, titled SKF InteractiveEngineering Catalogue , and online new edition of the General Catalogueisalso available electronically as well as inprintand includes many revisions, additionsand enhancements to make the catalogueeven more useful and valuable.

6 A familiariza-tion with the information in this foreword, aswell as other annotated sections, enablesthe user to obtain the maximum benefit fromthis comprehensive tool. This foreword discusses the main sectionsof the Catalogue with reference to majortechnical and product information as well asother available information of importance inunderstanding the overall capabilities of Catalogue overview This new SKF General Catalogue containsalmost all of the standard rolling bearings andaccessories required by industrial equipmentmanufacturers, as well as those used for re-placement purposes. To provide the highestlevels of service, SKF endeavours to have itsstandard assortment match virtually all cus-tomer needs and to have products availableon a worldwide basis.

7 The data in this Catalogue relate to SKF sstate-of-the-art technology and productioncapabilities as of early 2003. The data maydiffer from that shown in earlier catalogues because of redesign, technological devel-opments, or revised methods of reserves the right to make continuingimprovements to SKF products with respectto materials, design and manufacturingmethods, as well as changes necessitatedby technological units used in this Catalogue are in ac-cordance with ISO (International Organizationfor Standardization) standard 1000:1992,and SI (Syst me International d Unit s). Technical section principles of bearingselection and applicationThe technical section has a simplified indexallowing for easy identification of the separatechapters, which cover the basics of bearingtechnology as required for the design of abearing arrangement.

8 These chapters arearranged in the order normally followed by a design innovations in the technicalsection a new model for the determination of friction in rolling bearings. revised speed ratings for the thermallypermissible reference speeds based onthe new friction model. a new model for the determination of therequisite lubricant viscosity based onmore accurate knowledge of the influenceof raceway surface roughness and of theelastic deformation of the lubricant film. a new method to determine lubricant service life as well as the optimum relubri-cation intervals for grease-lubricatedbearings. the progress made in rolling bearing tech-nology and the experience accumulatedin practical applications in recent yearshave been taken into consideration andare referenced where appropriate in thevarious sections of the technical part.

9 SKF technical services related to thebearing, the machine, or even the com-plete manufacturing plant from bearingselection and calculation, to installation,monitoring, maintenance and replace-ment, are covered in a section referred toas Asset Efficiency Optimization. Product section bearing designations,descriptions and data The product section has a thumb index foreasy identification of bearing types. Theproduct tables contain all of the engineeringdata required for the selection of a bearingand its application. Information relating tothe specific types of bearings covered isarranged in front of the relevant producttable(s).

10 Notable innovations in the product sectionSignificant products included for the firsttime are: CARB toroidal roller bearings stainless steel deep groove ball bearings hybrid deep groove ball bearings ICOS bearing/seal units sealed spherical roller bearings high-temperature ball bearings and Y-bearing units INSOCOAT bearings NoWear bearings Solid Oil bearingsInvestigations have shown that factors suchas mounting, lubrication and maintenancehave a much greater influence on bearinglife than previously assumed. For this reason,new information has been included on thefollowing: SKF products for maintenance andlubrication SKF condition monitoring equipment andsystemsSeveral SKF innovations are worthy of par-ticular note as they offer many advantagesfor enhanced performance or greater pro-ductivity.
