  • Hydrodynamic low-torque lubricant seal with pumping projections
    Patent number: 5676383
    Abstract: An annular elastomeric sealing member includes a static sealing lip and a series of projections facing the lubricant. Each projection has a convex front surface that provides two oppositely facing pumping faces and an angled rear surface that intersects the front surface at an acute angle so as to form a sharp leading edge. The sharp leading edge on each projection has a relatively small radial clearance with respect to the cylindrical surface that is to be sealed. This small clearance enables the projections to exert pumping forces on lubricant proximate to the cylindrical surface.
