The invention belongs to the technical field of precision machine tools, and relates to an F-shaped retainer which is guided from two directions and has a high lubricating property. The retainer is used in a thrust cylindrical roller bearing, and the whole retainer is of an F-shaped structure, a square lubrication groove (10) and a semicircular lubrication groove (11) are arranged on an axial-radial guide surface of the retainer and the bearing race (3), and nineteen lubricating holes (12) are arranged in the axial direction. The invention has the beneficial effects of having axial-radial bidirectional guide, which restricts the axial and radial play of the retainer and improves the running smoothness of the bearing; having a composite lubrication structure, and prolonging the service life of the bearing.
