The characteristics of different types of spindles and linear slide systems and their influence on the workpiece accuracy are discussed. Aerostatic, hydrostatic and rolling element bearing systems are evaluated and compared. Taking the static, dynamic, geometric and thermal behaviour into account every bearing and guideway type has its advantages and disadvantages that define its optimum application. Based on measurement results of the component behaviour and analysed workpiece surfaces correlations are made to help the machine designer to choose the optimum bearing type for different applications.
