ABSTRACT:
A system for preloading the bearing of a cooling water pump for motor vehicles. The pump comprises a shaft and an impeller mounted on one end of the shaft and, an outer bearing ring surrounding the shaft. An axial face seal is mounted on one projecting end of the shaft operable bearing ring and to tension spring-loaded sliding rings with a predetermined contact pressure against each other. The outer axial end face of the axial face seal is aligned with the axial end face of the shaft to simplify and insert the same preloading of the bearing for assemblies put together by mass production techniques.
