  • Bearing gap determined depth and width
    Patent number: 9790990
    Abstract: Provided herein, is an apparatus that includes a fluid dynamic bearing defined in a gap between a stationary component and a rotatable component. The fluid dynamic bearing includes a first portion of the gap at an axial end of the fluid dynamic bearing, and a second portion of the gap. The first portion of the gap is narrower than the second portion of the gap. A groove in the fluid dynamic bearing on the stationary component or the rotatable component includes a portion of a predetermined width or a predetermined depth. The portion of the predetermined width or predetermined depth is selected based on the first gap or the second gap.
