ABSTRACT:
A seal is used between a housing and a shaft having an axis. The seal includes a first portion and a second portion engageable with each other and movable relative to each other. The first portion and the second portion are configured to be received in a cavity between the shaft and the housing. The first portion is engageable with the shaft such that the first portion is substantially stationary relative to the shaft and to inhibit passage of contaminants from the exterior of the cavity through the cavity toward the axis. The second portion is engageable with the housing such that the second portion is substantially stationary relative to the housing and to inhibit passage of the contaminants from the exterior through the cavity toward the axis.
