Abstract: A bearing assembly includes an inner ring and an outer ring that define a bearing interior between them and either the inner ring or the outer ring is fixed. When the inner ring is fixed, the inner ring includes at least one substantially radial through opening and when the outer ring is fixed, the outer ring includes at least one substantially axial and/or radial through opening, or at least one substantially axial and/or radial through opening is provided on a ring fixedly connected to the outer ring. The through opening is disposed between a 9 o'clock position and a 3 o'clock position on the inner ring when the inner ring is fixed or on the outer ring when the outer ring is fixed.

Abstract: A bearing includes a first ring, a second ring and a plurality of rolling elements between the first and second rings. The first ring is a split ring formed of a first ring part and a second ring part that meet at a joint region, and each of the ring parts includes a recess that extends axially into the respective ring part from the joint region. A cylindrical seal is disposed in the recess of the first ring part and extends across the joint into the recess of the second ring part.

Abstract: A bearing assembly includes first and second rolling-element bearings each having first and second bearing rings, a raceway and a flange element at both ends of the raceways. Two of the flange elements are formed on a common flange body, and the flange body is axially pressed onto cylindrical mounting surfaces of the first bearing rings of the first and second rolling-element bearings and held in place by a press fit.
