A method of forming a bearing cage segment includes determining a path of a periphery of the bearing cage segment along a metal sheet, punching a plurality of openings in the metal sheet inside the path to form a plurality of pockets separated by a plurality of bridges and separating the bearing cage segment from the metal sheet at the path. The separating includes laser cutting first and second joint edges at a first end of the row and third and fourth joint edges at a second end of the row, where the first joint edge is spaced from the second joint edge in a length direction of the bridges and the third joint edge is spaced from the fourth joint edge in the length direction of the bridges.

An outer contact surface element of a one-way clutch is configured to contact at least one clamping body of the one-way clutch when an inner ring of the one-way clutch rotates in a first direction. The outer contact surface element includes a hollow-cylindrical section, and at least one radially outwardly projecting lug. The outer contact surface element may also include features for connecting the outer contact surface element to a support bearing.

A sheet-metal bearing cage segment has a first ring section, at least one second ring section and a plurality of bridges connecting the first ring section and the at least one second ring section to each other such that a pocket for receiving at least one rolling element is formed between each circumferentially adjacent pair of the bridges. The first and/or second ring section includes at least one recess on the radially inner side and/or the radially outer side.

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.

Sealed universal joint bearing and universal joint bearing assembly

A structural unit for assembly to a trunnion of a universal joint bearing providing a cup, a sealing ring, which is fixed to the cup, and a shield, which is connected to the cup in a state in which the structural unit is not assembled to the trunnion. The cup includes a bottom and the sealing ring provides at least one sealing lip that points in a direction with an axial component towards the bottom.

A bearing cage segment of a sheet metal cage includes first and second sheet metal ring sections and bridges therebetween defining a plurality of pockets for receiving rolling elements. A first circumferential joint edge of the segment is configured to connect to a second circumferential joint edge of the segment or to a second joint edge of another segment, and the first joint edge includes at least one alignment element, such as a projection or contour, that is configured to align the first joint edge radially, axially and/or circumferentially against the second joint edge which may include a complementary alignment element such as a recess or complementary contour.

A sheet metal bearing cage segment includes a first sheet metal ring section, at least one second sheet metal ring section, and a plurality of bridges connecting the first ring section and the at least one second ring section to each other, adjacent pairs of the bridges forming pockets configured to receive at least one rolling element. At least one edge of the first ring section and/or at least one edge of the at least one second ring section and/or of one of the bridges is at least partially formed by laser cutting. Also a method of forming a sheet metal bearing cage at least partially by laser cutting.
