Abstract
A rocker arm (1) for a valve train of an internal combustion engine which is pivoted on a support pin (10) about its axis (9), whereby a push rod (7) contacts one end section (5), and the valve shaft (8) of a gas exchange valve contacts the other end section (6). The mounting of the rocker arm (1) on the support pin (10) takes place through two radial roller bearings (16) spaced at a distance from each other, whereby in a manner in accordance with the invention, an additional axial roller bearing (17, 18) is incorporated into the rocker arm bearing arrangement to prevent sliding friction.
