A spherical plain bearing is a bearing that permits angular rotation about a central point in two orthogonal directions (usually within a specified angular limit based on the bearing geometry). Typically these bearings support a rotating shaft in the bore of the inner ring that must move not only rotationally, but also at an angle. These are main types of spiral groove bearings. Cylindrical form journal bearings with a herringbone pattern of spiral grooves gives a bearing with excellent load capacity, resistance to cavitation and excellent stability. The symmetric herringbone pattern has zero flow which reduces the possibilit… movie where people are shrunk
