Abstract
A sealing arrangement includes a sealing ring ( ) having a sealing lip ( ) which is curved forward in the direction of the area to be sealed off ( ). The sealing lip ( ) is pre-tensioned so as to surround and form a seal around the circumference of the machine element ( ) to be sealed off. The sealing lip ( ) has, on the side facing radially away from the machine element ( ), at least one recess ( ). The recess ( ) only connects and allows flow between the area to be sealed off ( ) and the surrounding area ( ) if the sealing ring ( ) is incorrectly mounted and the sealing lip ( ) is erroneously curved forward in the direction of the surrounding area ( ).
