Abstract
A radial shaft seal for separating two media includes two radial shaft sealing rings each including an axial surface and a sealing lip. The sealing rings are disposed with the axial surfaces facing one another and the sealing lips axially opposed to one another with a space between the sealing lips including a vent. At least one of the sealing rings includes clamping cams configured to grip an inner rim of the other sealing ring so as to join the sealing rings in a form-locking, rear-engaging position relative to each other.
