ABSTRACT:
The tip edge of a second seal lip of an elastic member constituting a seal ring is in sliding contact with an outside face of a slinger. The seal ring and the slinger are pre-assembled and then installed between an inner peripheral surface at an end of an outer ring and the middle of an outer peripheral surface of a rotating shaft. The first and second seal lips are protected by the slinger prior to assembly. As a result, the first and second seal lips constituting the seal ring installed with the slinger can be installed without damage, using an industrial method.
