Cage segment of a tapered roller bearing, and tapered roller bearing

A first cage segment of a tapered roller bearing for rotatably supporting a first machine part relative to a second machine part, the first cage segment comprising:

• a first circumferential end and a second circumferential end;
• first and second mutually opposing circumferential bridges extending between the first circumferential end and the second circumferential end of the first cage segment, each of the first and second circumferential bridges having mutually facing pocket sides;
• first and second mutually opposing connecting bridges connecting the first and second circumferential bridges, each of the first and second connecting bridges having mutually facing pocket sides, the pocket sides of the circumferential bridges defining with the pocket sides of the circumferential bridges at least one pocket configured to accommodate a conical rolling element;
• and
• a projection at the first circumferential end of the first cage segment and a recess complementary to the projection at the second circumferential end of the first cage segment, the projection of the first cage segment being configured to mate with a recess of a second cage segment adjacent to the first cage segment and the recess of the first cage segment being configured to mate with a projection of a third cage segment adjacent to the first cage segment;
• wherein
• the pocket sides of the connecting bridges are concave and configured to guide a rolling element, and
• the first cage segment is configured to be rolling-element guided.
