The invention relates to a processing technique for a super-huge type tapered roller bearing precision product, belonging to bearing manufacture technology. The technique is implemented by processing a roller by using a standard roller; processing an inner raceway according to a standard inner race; processing an inner arc flange by using an inner race standard shape template; dyeing the roller to be assembled until the spherical fiducial surface of the assembled roller touches the middle position of the inner arc flange; processing the size and angle of an outer raceway according to a standard piece, assembling the inner race and the roller according to a finished product state, and coloring the processed outer race and the inner component composed of the inner race and the roller; assembling the outer race and the inner component composed of the inner race and the roller; judging the angle of the raceway according to the position where the color of the raceway is scraped off so as to adjust the angle of the machine tool; when the color scraped by the outer raceway is uniform, leading the angle of the raceway and that of the inner component to be consistent. With the technique ofthe invention adopted, once assembly success rate can reach up to 100%, the production efficiency is enhanced, and the end circular run-out of the super-huge type tapered roller and the finished product precision requirements are guaranteed.
