Component for use in a bearing device and a method for forming a lubricant layer

A component for use in a bearing device, including a lubricant layer on a surface of the component, the lubricant layer containing a rod-like ionic liquid crystal compound having a cation group and an anion group,

• the bearing device including:
• a rotating body, having a rotary body surface, configured to extend vertically to a rotating axis;
• a static body having a static body surface facing in axial opposition to the rotary body surface;
• a lubricant present in a gap between the static body surface and the rotary body surface;
• and
• a thrust dynamic pressure groove configured to generate a thrust dynamic pressure in the lubricant, the thrust dynamic pressure groove being provided in at least one of the static body surface and the rotary body surface,
• wherein said component is at least one of the rotating body and the static body,
• wherein, when said component is the rotating body, the lubricant layer is provided on the rotary body surface, and
• wherein, when said component is the static body, the lubricant layer is provided on the static body surface.
