Abstract

Sealing element consisting of a body with at least one synthetic sealing lip provided to it. This synthetic sealing lip is pressed against the part that moves in relation to the part in which the body is provided. This pressure is realized with the aid of a spring. To spread the load in the spring evenly, the spring is made such that the moment of resistance against bending is substantially constant across the full extent of the spring.
