Abstract

A shaft seal has a rotary seal and a stationary seal with predetermined axial and radial dimensions. The two seals are positioned, with respect to a shaft, so as to fix the axial and radial dimensions with respect to one another by way of a plastic strip which is positioned about the sleeve of the rotary with its edges engaging the rotary and the stationary seals and extends to the exterior thereof. A tab is provided at the end of the plastic strip and the strip is pulled from the seal after axial and radial fixation of the seal components and upon rotation of the shaft.
