Abstract

PURPOSE:To improve sealing property and durability by forming in one or both of sliding faces of a seat ring and a driven ring an annular groove with its center coinciding with the center of an axis. CONSTITUTION:Sliding faces 3a, 5a of a seat ring 3 and driven ring 5 are extremely finely lapped up to the roughness 0.1-1.0mu and an annular groove 6 is formed around the center of an axis in the sliding face 5a of the driven ring 5. By constantly keeping lubricating oil in the annular groove 6, an oil membrane is formed and maintained even during a stop of revolution of the mechanical seal 1.
