Patent ID: 8348512

Claim:
A clutch release bearing device comprising: a first bearing race representing a bearing race revolving around a bearing axis and forming a first rolling member race section formed as an external ring surface, a second bearing race forming a second rolling members race section formed as an internal ring surface, rolling bodies contained in a raceway space defined between the first bearing race and the second bearing race, a cage guiding the rolling bodies within the raceway space, the first bearing race and the second bearing race overlapping one another in an axial direction, and the second bearing race externally surrounding the first bearing race, on the second bearing race, a radial drawn-in ring wall being formed below a radial level of the first rolling member race section, and a sealing device for suppressing penetration of dirt into the raceway space, as well as for suppressing escape of lubricant through a potential passage section formed between both the first and second bearing races, the sealing device comprising a ring element sitting on an internal wall section of the radial drawn-in ring wall of the second bearing race, wherein the ring element comprises a sealing structure made of an elastomeric material and forming a sealing lip device, wherein the sealing lip device comprises a sealing lip pair with a first sealing lip and a second sealing lip, the first sealing lip being a main sealing lip that is radially spring loaded against an external circumferential section of the first bearing race and the second sealing lip formed as a non-contacting or only lightly contacting dust prevent sealing lip that functions as a pre-sealing lip at a race section formed as a ring face of the first bearing race.
