Abstract
A rock bit seal in which the shape of the retainer lip (which restrains the seal from axial motion in response to pressure differentials) is optimized, with respect to the as-deformed shape of the seal in place, to achieve a preload stress which is everywhere nonzero. Preferably the ratio of maximum to minimum stress in the as-installed condition is kept to a small ratio, e.g. less than 2:1.
