Abstract

A planetary carrier for a gear stage of a planetary gearset includes at least one planetary pin that is disposed in a rotationally fixed manner in the planetary carrier, and a pair of tapered roller bearings that are disposed on the planetary pin supporting a planet gear. The planetary pin is fastened by a pin screw connection, which comprises a pin screw and a nut, to the planetary carrier. The tapered roller bearings are clamped against each other between the planetary carrier and the planet pin and are axially pretensioned by the pin screw connection.
