Abstract
An apparatus includes a stationary sleeve and a shaft operable to rotate with respect to the stationary sleeve. A hub rotates with respect to the stationary sleeve in response to the shaft rotating. A mechanically adjustable gap forming component is attached to the stationary sleeve and radially extends between the hub and a base. The mechanically adjustable gap forming component forms a radially extending gap above the mechanically adjustable gap forming component. The mechanically adjustable gap forming component is mechanically adjustable in an axial direction with respect to the stationary sleeve. The hub dynamically adjusts the radially extending gap above the mechanically adjustable gap forming component during rotation of the hub.
