The invention relates to an axial bearing in a drivetrain having an internal combustion engine with a crankshaft and having a transmission with at least one transmission input shaft, comprising a first bearing ring arranged at the engine side and comprising a second bearing ring arranged at the transmission side, and comprising rolling bodies which roll between the bearing rings. To propose radial offset compensation of the components connected to the bearing rings, rolling bearing surfaces which are provided in each case with a first rolling radius are arranged in the bearing rings so as to be distributed over the circumference, on which rolling bearing surfaces tilting pins which are designed in each case as rolling bodies roll, so as to be tiltable to a limited extent about their longitudinal axis, by means of second rolling radii which are provided on both end sides and which are in each case complementary to the first rolling radii. The invention also relates to a drivetrain in which a corresponding axial bearing is provided for the support of a torque transmission device against the crankshaft.
