Abstract
A connection of a bearing bolt () in a cylindrical housing () of a roller tappet () that is actuated in a direction of a longitudinal axis (Z) is provided, especially for a tappet push-rod valve drive of an internal combustion engine. The bearing bolt () is supported in bore holes () of the housing (), which extend in a transverse plane (XY) to the roller tappet (), perpendicular to the longitudinal axis (Z), and is connected with a positive and/or non-positive fit to the housing () through material deformation. The material deformation is provided as one or more segments (), of which at least one segment () completely encloses a radial load zone () of the bearing bolt (), and a section () of the bearing bolt () extending about the transverse plane (XY) is free from material deformation.
