Abstract：As a core component of high-end equipment,spherical plain bearings transmit loads and enable complex motions such as tilting and oscillation,and widely used in critical fields like military and aerospace.Their precision forming technology directly determines the forming quality and service performance of spherical plain bearings.Two common forming processes for integral self-lubricating spherical plain bearings were introduced:Mold extrusion forming and rotary extrusion forming.The application of finite element analysis in process optimization is briefly discussed.The current state of forming technology both domestically and internationally for integrated self-lubricating spherical plain bearing is summarized.Finally,future development trends are outlined:focusing on"high precision and damage-free"as core objectives,and performing multi-objective optimization of forming processes through iterative optimization algorithms to ensure normal operation under extreme conditions such as high temperatures and corrosion.This involves developing novel forming processes by integrating advanced technologies like 3D printing.
