A FEM simulation software has been used to simulate the bearing outer rings ’ closed-die forging process.Effect of per-form on metal flow,force of punch ,stress,strain and temperature has been studied.For the purpose of improving deformation uni-formity and reducing the force of punch ,a reasonable preform is obtained ,which provides a basis for closed-die forging of bearing rings and similar parts.
