Abstract: A method of forming a bearing assembly includes providing a bearing unit configured to support a rotatable component relative to a stationary component, the bearing unit including a stationary bearing ring and a rotatable bearing ring, and overmolding a material onto a portion of a radial surface of the stationary bearing ring, the portion being less than an entire radial surface of the stationary bearing ring, for example less than 75% of the entire radial surface of the stationary bearing ring, to form the stationary component.

Abstract: A non-locating bearing assembly includes a bearing unit configured to support a rotating component relative to a stationary component, and the bearing unit includes a first stationary bearing ring and a second rotatable bearing ring that is fixedly connectable to the rotating component. The bearing assembly also includes a bearing carrier to which the stationary bearing ring is attached in a rotationally fixed but axially displaceable manner, and the bearing carrier is configured to be fixedly connected to the stationary component.

Abstract: A bearing assembly includes a bearing having a first bearing ring, a second bearing ring rotatably disposed relative to the first bearing ring, and a plurality of rolling elements in a bearing interior defined by the first bearing ring and the second bearing ring. Also, at least one layer of non-metallic material on the first bearing ring configured to conduct heat away from the first bearing ring and to electrically insulate the first bearing ring and to fill at least one cavity between the first bearing ring and a component to which the first bearing ring is mounted. The at least one layer may be a first layer of a heat-conducting material and a second layer of a different, electrically insulating material.

Abstract: A method for installing a bearing assembly on a stationary component where the bearing assembly includes a bearing carrier, a stationary bearing ring rotationally secured to the bearing carrier and a rotatable bearing ring supported for rotation relative to the first bearing ring. The method includes inserting a portion of the bearing carrier into an opening in the stationary component or inserting a portion of the stationary component into the bearing carrier, using an alignment tool to position at least two exposed radial surface portions of the stationary bearing ring with a surface of the stationary component to produce a temporary alignment of a rotational axis of the stationary bearing ring with a central axis of the stationary component, after producing the temporary alignment, attaching the bearing carrier to the stationary component in a manner that maintains the alignment, and removing the alignment tool from the bearing ring.

Abstract: A sealed universal joint bearing includes a pot-shaped component having a disk-shaped base and a cylindrical wall projecting from a periphery of the base, and an inner surface of the base and an inner surface of the cylindrical wall define an interior of the pot-shaped body. At least one row of rolling elements are configured to roll along the inner surface of the cylindrical wall. A flange in the interior of the pot-shaped component has a flange surface against which end sides of the rolling elements are configured to slip during bearing operation, and the flange surface includes at least one formation configured to reduce a contact area between the flange surface and the end sides of the rolling elements.

Abstract: A retaining element configured to retain an outer ring of a bearing in a housing, the retaining element having a body having a first side and a second side and a substantially circular through-hole extending from the first side to the second side and an axial thickness from the first side to the second side. A boundary of the through-hole includes two or fewer recesses. The retaining element is configured to hold an attachment element in the two or fewer recesses, the attachment element being configured to engage a groove in a bearing to hold the bearing in the retaining element.
