Abstract
A two-part dual lip, reversible seal for gear cases and the like wherein a peripheral seal is to be established about a shaft which passes into the housing. Each part of the seal is of semi-circular configuration consisting of a metal retainer and an elastomeric sealing portion which is formed as an integral unit and which is positioned and retained in appropriate channels in the gear case. The elastomeric seal comprises dual sealing lips having a recess therebetween for charging with lubricant prior to assembly of the housing over the gears and shaft. Projection of the seal element at either end of its circumferential extent allows for controlled compression of the elastomeric material in engagement with the mating part of the seal and a continuous seal about the periphery of the shaft.
