Patent ID: 8220998

Claim:
A fluid dynamic bearing system having a stationary bearing component ( 12 ; 22 ) and a moving bearing component ( 14 ; 20 ) that are separated from one another by a bearing gap ( 18 ) filled with a bearing fluid and disposed rotatably with respect to one another about a rotational axis ( 48 ), wherein two radial bearing regions ( 24 ; 26 ) separated axially from one another and marked by radial bearing grooves ( 25 ; 27 ) are provided, wherein a separator region ( 29 ) having a larger bearing gap width is located between the radial bearing regions ( 24 ; 26 ) and wherein the radial bearing grooves ( 25 ; 27 ) of the two radial bearing regions ( 24 ; 26 ) have inner ends facing each other and outer ends facing away from each other, and at least the outer ends of the radial bearing grooves ( 25 ; 27 ) are connected to each other by connecting grooves ( 34 ; 36 ), wherein wear zones ( 38 ; 40 ) are provided adjoining the connecting grooves ( 34 ; 36 ).
