economic leadership The starting point and objective of all activities in the company is proximity to and benefit for the customer. Precise knowledge of specific application requirements and processes is the decisive factor in selection of the technically optimum product that also incurs the lowest system costs. This may be sourced from the fully developed standard range of spindle bearings, which is unsur- passed in its scope worldwide. Equally, it may lie in an individual, application-specific solution that is provided rapidly and reliably FAG super precision bearings set standards in...

The right material FAG super precision bearings are made from high quality materials. Through specific heat treatment, a long material fatigue life and wear resistance is achieved with the result that the bearings can be run permanently in many cases. There is a particular role for the material Cronidur 30, which turns a spindle bearing into an X-life ultra bearing. With its unique characteristics of reverse bendingstrength and corrosion resistance, it achieves significantly extended life, higher permissible contact pressures for fatigue strength, higher permissible speeds and significantly...

About this catalogue Catalogue SP l gives an overview of the FAG product range of super precision bearing arrangements as well as the most important rules covering bearing selection, bearing arrangement design and One function of the catalogue is to present the product range of FAG super precision bearings for main spindles. In addition, it is also intended as a technical compendium forthe selection and design of bearing arrangements using super precision bearings. This catalogue brings together the most important technical principles for the designer. It thus gives a transparent...

Load carrying capacity and operating life Super precision bearings must guide machine parts with high precision and must support forces securely at very high speeds. The bearings are therefore selected predominantly according to the criteria of accuracy, rigidity and running behaviour. In order that they can fulfil these tasks securely, they must run without wear. This requires the formation of a load-bearing hydro- dynamic lubricant film at the contact points of the rolling contact partners. Under these conditions, the bearings will achieve their fatigue life in a large number of...
