ABSTRACT:
An improved sealing surface configuration consists of a grid-like pattern of indentations formed into the surface, uniformly spaced to create a consequently uniformly spaced series of intermediate seal support pads. Each indentation includes a sloped wall converging with an adjacent pad in the direction of seal lip motion. The consequent hydrodynamic pumping action pumps lubricant out of the indentations and over the pads, creating a uniform lip supporting film to reduce friction. A method of deforming and machining the sealing surface to produce the configuration is also disclosed.
