Field of the Invention The present invention relates to a nut manufacturing method, and a new type of bearing nut fitting can be proposed with respect to a nut and can be easily manufactured and processed. The bearing sleeve and the brake bearing ball screw are disposed on the outer side thereof, and the structure of the invention enables the bearing nut to reduce the ^^ 轴 axis, and the current method is caused by the left left shaft groove, and then the lock is fixed. In the assembly, the technology] The bearing ball is sleeved on the screw to separate the side bearing and the geometry. After the pre-loading and pre-pressing, the nut is separated, so that the assembly needs to have a bearing. The nut can be rotated, and the mesh can not be directly assembled on the nut, so it is assembled by pre-compression. And this is done: the side bearing and the intermediate pre-pressing piece are not processed at the same time, and the error is easy to cause the concentricity of the bearing after assembly. The bearing structure of the off-type bearing is processed by the inner diameter bead groove, and the right bearing is first locked together to process the inner diameter of the bead j parts, respectively, on the nut, and finally, the machining process is complicated. And the number of parts produced by the parts is increased. SUMMARY OF THE INVENTION Part. ^3 : 2:! Mainly includes bearing nut and bearing sleeve two bearing sleeves ^ 廿" 0 outer circumference of the bearing is designed into a one-piece forming structure diameter drilling: through filling: the capacity of the ball "raw, and the bearing sleeve The outer bearing type screw r = fading beads can be loaded from the outside of the bearing sleeve, so that the type of scarf 1 can reduce the accessories and fill the balls lightly and time-saving.
