1) In a mechanical sense, it refers to the part of a machine that allows for motion by reducing friction between moving parts. This is commonly known as a "pillow block," "ball bearing" or "roller bearing."
2) It can also refer to the manner in which someone carries themselves or behaves towards others - their demeanor, conduct or behavior.
3) In astronomy and navigation, it refers to the angular distance between two points measured on a great circle (the shortest path between two points on a sphere). This is often expressed as "bearing" in degrees from north, south, east or west.
