ABSTRACT:
A sealing device is adapted to be disposed between a stationary part and a rotary shaft in the stationary part so as provide a seal in the gap between the stationary part and the rotary shaft. The sealing device has a slinger secured to one of the stationary part and the rotary shaft and a rubber seal secured to the other of the stationary part and the rotary shaft and provided with a lip which makes a resilient pressure contact with the slinger. When the rotation speed of the rotary shaft is increased, centrifugal force is increased to cause a tendency to decrease the pressure of contact between the lip and the slinger so that the wear of the lip is prevented to improve the durability of the sealing device. In addition, the resistance torque produced by the sealing device is not increased substantially even when the speed of rotation of the rotary shaft is increased.
