Abstract: Method of rolling outer races of bearings in a die by means of a rolling tool roller operating under overhanging conditions in a blank of the race to be rolled, which consists in cold treating the race blank having a smaller diameter than said die, the treatment comprising preliminary rotating the roller at its contemplated rolling speed in the blank and, under constant stress conditions, causing the roller to penetrate into the blank, rolling this blank until the die is filled therewith, upsetting the blank material laterally while gauging the race, and then producing an initially slow backward movement of the roller in order to preserve the aforesaid gauging.

Abstract translation: 通过在待轧制的滚道的坯料中在悬垂条件下工作的轧制工具辊来轧制模具中的轴承的外圈的方法，其包括对具有比所述模具更小的直径的滚道坯料进行冷处理，所述处理包括 以预定的轧制速度将辊旋转到坯料中，并且在恒定的应力条件下，使辊子渗透到坯料中，轧制该坯件直到模具被填充，同时在测量该种族时侧向镦粗坯料，然后 产生辊的最初缓慢的向后运动，以便保持上述测量。
