A spindle system is comprised or a journal and thrust air bearing. The journal bearing; has two sets of opposing groove areas. The thrust air bearing has two sets of spiral grooves. The thrust air bearing is gimballed to compensate for misaligment. A bias contact member is connected to the rotating member along the axis of rotation and provides electrical grounding, The spindle system is especially applicable to mounting recording disks in a data storage disk drive.
