For the obvious missing angle problem on the outer surface of bearing tubes by equal-pitch spiral rolling cutting, according to the spiral rolling theory, the quantitative relationship between arbitrary radial reduction and axial extension was clarified, and methods to improve hole filling were explored by gradually reducing the screw pitch to reduce axial extension deformation,and a variable pitch rolling model that strictly controlled the amount of missing angles was established. Then, using rigid-plastic finite element numerical simulation technology, it was confirmed that the axial and radial missing angle rates within 4% was obtained by the variable pitch method, and after adding a guide plate to limit lateral deformation,it not only continued to reduce the missing angle rate, but also improved the tube roundness to 1.01. The rolling force and rolling moment of the variable pitch and equal pitch methods showed a gradual increase in volatility, and the average pressure and moment were 15.2, 18.2 kN, 914.4 and 884.5 N·m, respectively, with difference of approximately 16.4% and 3.3%. Thus, the research results had certain theoretical and practical significance for high-precision cutting of bearing tubes.
