A fluid seal of the type employing a groove pattern on one of the opposed seal faces, which groove pattern includes a series of angled grooves formed in and positioned circumferentially around one of the seal faces, with the configuration of the grooves and of the flat face lands defined between adjacent grooves being configured to improve the squeeze film effect over the lands and between the opposed faces. The angled grooves are formed such that the sides of adjacent grooves extend generally in parallelism with one another so that the intermediate land area between adjacent grooves maintains a substantially constant width, even adjacent the radially inner ends of the grooves.
