  • Patent number: 6814356
    Abstract: A mount construction for a bearing seal is capable of easily and surely installing the bearing seal in a bearing and, after installation, developing a stable seal performance by suppressing an extracting force. The bearing seal, formed by disposing an elastic member having a lip part on one side face of a reinforcement ring, is press-fitted into a ring body or radially reduced ring body in a state where the lip part is bent in a direction away from the outer peripheral edge of the reinforcement ring on the elastic member side of the bearing seal. While maintaining this state, the bearing seal is extruded from the inside of the ring body or the radially reduce ring into the bearing with care so that the lip part is not caught between the reinforcement ring and the bearing is installed on the bearing.
