Abstract
A method for fixing an axle within a roller tappet in which a preload is applied to the axle in a direction perpendicular to its longitudinal axis while the ends of the axle are deformed into chambers formed in the ends of the axle-receiving aperture in the tappet body. In accordance with a preferred embodiment of the invention the axle ends are deformed by an orbital staking process.
