1. A centrifugal pendulum for a motor vehicle drivetrain, comprising a carrier and a pendulum mass, which is mounted for pivoting relative to the carrier by means of at least one roller body, wherein a first rolling region of the at least one roller body is accommodated in a roller track of the carrier and a second rolling region of the at least one roller body is accommodated in a roller track of the pendulum mass, wherein at least one of the two roller tracks is formed partly or completely by an axially formed sheet-metal portion in such a way that a free edge of the axially formed sheet-metal portion faces away from the nearest pendulum mass; wherein the formed sheet-metal portion has an area curved by sheet-metal forming, with which a portion of the roller body can be brought into contact and over which the portion of the roller body rolls.
