Abstract: A sealing device is provided for sealing a space between a hub and a spindle pivotally connected by a bearing, the hub being coaxially mounted on the spindle and extending in an axial direction and the bearing having an inner ring. The sealing device includes a radial shaft seal including a shell portion having an outer static sealing surface disposeable against the hub and a hinge portion having a radial sealing lip. A sleeve member includes an inner static sealing surface disposeable against the spindle, a running surface contactable by the sealing lip and a sleeve portion. The sleeve portion extends in the axial direction beyond a side surface of the bearing inner ring and is disposeable about a shoulder diameter of the bearing inner ring.

Abstract: A bearing assembly includes a first bearing comprising a first inner ring and a second bearing comprising a second inner ring. A sleeve-shaped spacer is disposed between and axially separates the first and second inner rings. An adhesive connects the spacer to the first and second inner rings.

Abstract: A bearing assembly comprises at least two axially-spaced bearings, each bearing including an inner ring. The at least two inner rings have differently-sized bore diameters. A sleeve-shaped connecting piece having a substantially frustum, conical or tapered shape is disposed between the two inner rings. An inner diameter of the connecting piece at its respective axial end regions corresponds to the respective bore diameter of the bordering inner ring so that first and second contact points are defined between the connecting piece and the respective inner rings. First and second curved or ring-shaped fixing elements are respectively disposed at the first and second contact points so as to fix the inner rings relative to the connecting piece in the radial direction of the bearing assembly. Each fixing element at least partially axially overlaps the connecting piece and the respective inner ring.

Abstract: A bearing assembly includes a first bearing comprising a first inner ring and a second bearing comprising a second inner ring. A sleeve-shaped spacer is disposed between and axially separates the first and second inner rings. The spacer has at least one at least partially circumferentially-extending cantilever arm extending from at least one axial end of the spacer and is configured to at least partially overlap one of the first and second inner rings in the axial direction. The cantilever arms may be annular-shaped and may engage the respective first and second inner rings in a location fit or an interference fit.
