A seal for a thrust shaft in a body wherein the body has a bore and a counterbore, the bottom of the counterbore providing a shoulder for the thrust force of the shaft. The seal includes a bearing sleeve which is slidably mounted on the shaft, the bearing sleeve having a static O-ring which seals the interior of the sleeve to the shaft and a flange which extends into the counterbore. Provision is made for radially fixing the bearing sleeve to the shaft. A ring-shaped seal housing is mounted about the shaft below the bearing sleeve and extends into the counterbore, the seal housing having an interior dynamic O-ring sealing the housing to the shaft and an exterior static O-ring which seals the housing to the counterbore.
