Abstract
A tapered roller bearing includes cage segments each having a pocket that retains one conical rolling element. The pocket is formed by two mutually-opposing circumferential bridges, which each extend between first and second circumferential ends of the cage segment, and at least two mutually-opposing connecting bridges, which connect the two circumferential bridges. The circumferential and connecting bridges have pocket sides, which delimit the pocket. The connecting bridges disposed in the region of the first and second circumferential ends each have a concavely-shaped first guide surface on their pocket and circumferential sides that partially enclose one rolling element. When a rolling element is disposed between the first circumferential end of one cage segment and the second circumferential end of the adjacent cage segment, the circumferential bridges of the two adjacent cage segments do not touch during operation.
