On the basis of analyzing the structure features of thrust bearing, using the method of numerical simulation，the metal flowing characteristics were researched during the thrust bearing forming by warm extrusion .The simulation results show that the metal flow smoothly without any forming defects and the metal filling station of the three convex parts is good. Taking into account of numerical simulation results, the route of warm extrusion process was determined and the billet structure size is Ф86 mm×Ф26.2 mm×46mm. The forming die was designed. Using a punch with a spindle structure, the punch mandrel size is Ф26mm×50mm.The composite structure of the die is propitious to form three convex plates and disengage the part from the top die. The structure of the stripper plate is designed to be operated easily.
