Abstract (en)

[origin: WO2014180668A1] The invention relates to a roller bearing (100), in particular a roller bearing (100) with a diameter greater than 50cm, comprising an inner ring (110), an outer ring (120), a number of rolling elements (130) located between the inner ring (110) and the outer ring (120), and at least one sealing ring (140). The sealing ring (140) is arranged on a surface of the inner ring (110) or of the outer ring (120) and the outer ring (120) or inner ring (110) comprises a corresponding recess. The recess is designed and arranged in such a way that a major part of an exposed surface of the sealing ring (140) is enclosed in a contactless manner, such that, between an interior, used for accommodating the rolling element (130), and an exterior of the roller bearing (100), a labyrinth seal is formed by means of the sealing ring (140) and the recess.
