Moreover, the radial lash permits an autorotation of the bearing pin relative to the reception bore to the benefit of a uniform surface loading in {HEAD ~ the region} of the roller, so that safety from surface wear in the contact region between {TAIL ~ the bearing pin} and the roller, including any rolling elements that may be used, is further improved
