Abstract

The invention concerns a sealing arrangement (1), for sealing of a radial gap between relatively rotatable inner and out components, whereby the inner component (3) is rotational about an axis of rotation (a) and the outer component (4) is coaxially arranged around the inner component (3). The sealing arrangement comprises: a dynamic seal part (12) that is mountable to the inner component (3); a static seal part (10) that is mountable to the outer component (4); and first and second labyrinth seals (5, 6), each of which is formed by a gap between at least one set of opposing surfaces on the static and dynamic seal parts. According to the invention, the sealing arrangement (1) further comprises a lip seal (7), which is arranged radially between the first (5) and the second (6) labyrinth seal. The lip seal comprises a sealing lip (8) which is connected to the dynamic seal part (12) and which bears against a radially oriented counterface on the static seal part. Furthermore, the sealing lip (8) has a longitudinal extension (L) in a radial cross section that extends towards the rotation axis (a) at an angle (α) of between 10° and 80°.
