About this catalog

This catalog (FAG AC 41 130/7) presents the product range of FAG Super precision bearings for main spindles. It is further designed as a technical compendium for the selection and design of bearing arrangements utilizing high precision bearings. The principal engineeringrelated information for the designer is summarized and accessible. The clear structure, numerous crossreferences and the subject index at the end make it easier for students and “young colleagues” in training to enter the world of high precision bearing arrangements. For the experienced user of Spindle bearings, it provides a ready presentation of all Components, expertise and services offered by the Schaeffler Group.

The catalog is provided in 8 languages (German, English, French, Italian, Spanish, Czech, Chinese and Japanese) and is available in all languages on a CD-ROM of the same name.

The catalog is divided into six parts. Following the introduction, the chapter “Bearing Tables” lists the complete product range of Super Precision Bearings. The important technical characteristics and performance features are described in tabular form. This section is structured based on the different bearing types: Spindle, Cylindrical Roller, Floating Displacement and Double Direction Angular contact thrust ball bearings. A short introduction to the bearing forms, design types and a description of nomenclature is provided at the beginning of the bearing tables. The “Tolerances” chapter follows the table section and contains information about the bearings ings Bear and their mating parts.

In the following “Engineering” chapter, the necessary steps and calculation methods for selecting and designing a spindle bearing arrangement are presented. The calculation of service life, lubrication life, limited speed and rigidity are given particular attention. The necessary methodological steps for concrete application engineering design of a spindle are presented in the “Bearing arrangement design” chapter. The mounting of spindle bearings requires special attention regarding procedure, accessories and environmental conditions that must be maintained. These are addressed in detail in the “Mounting guidelines” chapter. In addition to the “Standard range,” the Schaeffler Group offers customer-specific bearing solutions in the high precision sector. Options are described in the “Customised Solutions” chapter.
