Abstract: A rolling bearing cage has at least a first end face with at least one elevation. The at least one elevation differs from an individual step which has a right angle in one section. In other words, the elevation has a shape different than a single step with a right angle.

Abstract: An assembly includes a fastening screw having an end surface and a substantially cylindrical side surface extending axially away from the end surface and a protective cap covering the free end. The cap has a first end opening from which the fastening screw extends, a second end overlying the end surface of the fastening screw, a side wall surrounding a portion of the cylindrical side surface, an inner surface defining a cap interior, and an outer surface. A cap screw extends through an opening in the second end of the cap and into a threaded opening in the end surface of the fastening screw to secure the protective cap to the fastening screw.

Abstract: A structural unit includes a cylindrical component and a metal-plate element having a through-neck, and the cylindrical component extends though the through-neck and is attached to the cylindrical component. The through-neck substantially determines a position of the metal-plate element relative to the cylindrical component with respect to a radial direction of the cylindrical component. Also an oil mist separator including the structural unit.

Abstract: A rolling-element bearing assembly includes an inner race and an outer race and a plurality of rolling elements between inner and outer races, the rolling elements being mounted in pockets between axial bridges of a cage having first and second axial side rings. One or both of the side rings has at least one corrugated surface, and the corrugations project axially and/or radially.

Abstract: A bearing support includes at least one sliding bearing defined by the bearing support and/or at least one rolling-element bearing having an outer raceway defined by the bearing support. The bearing support is formed from a fiber-plastic composite and includes an integrally formed sliding surface of the sliding bearing and/or an integrally formed raceway for rolling elements of the rolling-element bearing, and the fiber-plastic composite includes a matrix into which spatially oriented sliding fibers, for example, PTFE fibers, are embedded in a region of the sliding surface of the sliding bearing and/or a region of the raceway of the rolling-element bearing.

Abstract: A split bearing cage for a rolling-element bearing assembly includes a first bearing cage segment and a second bearing cage segment each having two side ring sections axially spaced apart by a plurality of bridges. Adjacent pairs of the bridges define rolling-element receiving pockets for receiving rolling elements of the rolling-element bearing assembly and for holding the rolling elements spaced apart from each other and for guiding the rolling elements. The first bearing cage segment is connected to the second bearing cage segment via a swivel joint that may be formed of a bolt element on a first end of the first bearing cage segment and an at least partial eyelet on the first end of the second bearing cage segment.

Abstract: A bearing cage for a rolling-element bearing includes a plurality of bearing cage segments configured to receive rolling elements in rolling-element pockets. Also included is at least one assembly wire, and each of the cage segments includes a coupling arrangement configured to thread the bearing cage segment onto the at least one assembly wire such that at least one rolling-element pocket is formed by two of the plurality of bearing cage segments adjacent in the circumferential direction that are threaded on the assembly wire. The bearing cage also includes an assembly device configured to convey an end of the assembly wire from an installation position to an axially far-side coupling arrangement of a bearing cage segment, through the axially far-side coupling arrangement of all bearing cage segments located on a bearing inner ring, and back again towards the installation position.

Abstract: A bearing cage for a rolling element bearing includes a plurality of individual bearing cage segments configured to respectively accommodate rolling elements in rolling element pockets formed by the bearing cage segments. Each bearing cage segment includes a first coupling device disposed on a first axial end thereof. A first lamellar support ring defines first and second ring halves that are connected to each other, are axially adjacent to each other are biased towards each other. The first ring half extends through the respective first coupling devices of the plurality of bearing cage segments and the second ring half is disposed on an axially-inner side or an axially-outer side of the first coupling devices such that the first coupling devices are clamped between the first and second ring halves.
