1) Short-term oil/grease leakage at the oil seal is possible in the run-in phase (168 hours running time).
2) During the run-in phase, the sealing lip grinds on the shaft and produces a path with a smoothed surface. Once the run-in phase has
been completed, the prerequisites for proper functioning of the seal are fulfilled.
