Provided is a tapered roller bearing (1) for which a dimensionless number X is defined by the following formula (1) based on a small-diameter-side gap S1 which is a gap between a small-diameter-side annular part (6) of a retainer (5) and a small collar part (2b) of an inner ring (2), a large-diameter-side gap S2 which is a gap between the large-diameter-side annular part (7) and a large collar part (2c) of the inner ring (2), an average roller diameter d, a roller length l, and an outer member angle α. The dimensionless number X falls within a range of 0.69<X<1.12.

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 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.

The present invention relates to a joint assembly for a driveshaft comprising, a yoke stub (1) with multiple channels (3) in the direction of extension; a tube sleeve (2) is having a recess (4) aligned corresponding channel (3) and telescopically engaged with a yoke stub (1). The driveshaft further comprises multiple rollers (14) spaced apart from each other in such a way that providing axial movement between the channel (3) and the corresponding recess (4) to transmit torque and a cage (12) extending between the rollers (14) to secure them together.

A method of forming a bearing cage segment includes punching a plurality of openings in a sheet metal band to form a plurality of pockets separated by a plurality of bridges, the bridges having a length direction transverse to a length direction of the band and having a width in the length direction of the band and having a thickness in a direction perpendicular the length direction and to the width, and laser cutting the sheet metal band along one of the plurality of bridges transversely to the length direction of the band to form a joint edge.

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.
