Abstract
The invention relates to a fluid dynamic bearing system having a stationary bearing component and a moving bearing component, that are separated from one another by a bearing gap filled with a bearing fluid. There are two radial bearing regions separated from one another and marked by radial bearing grooves. A separator region having a larger bearing gap width is disposed between the radial bearing regions. The radial bearing grooves of the two radial bearing regions have inner ends facing each other and outer ends facing away from each other. At least the outer ends of the radial bearing grooves are connected to each other by connecting grooves. According to the invention, wear zones provided especially for this purpose are disposed adjoining the connecting grooves, so as to prevent material wear at other regions of the bearing.
