A method of manufacturing a lift transmitting component (2), particularly for a gas exchange valve train or a fuel pump drive of an internal combustion engine (1), is provided, The lift transmitting component includes a housing (6), a bearing pin (7) fixed in a reception bore (9) of the housing (6) and a roller (8) mounted through a sliding or a rolling bearing on the bearing pin (7). The bearing pin is core-hardened over an entire axial length to a core hardness of at least 650 HV, and pin ends (10) of the core-hardened bearing pin are radially widened relative to the reception bore for enabling a connection of the bearing pin to the housing (6) through positive engagement. The hardness of the bearing pin is at the most 780 HV, the radial widening of one of the pin ends being realized with a shaping die (11) which travels axially parallel to the bearing pin (7) and applies a force to the pin end in a transition region between a periphery and a front end surface of the bearing pin.
