The REBDW-12 self-lubricating radial spherical bearing underwent finite element analysis using Solidworks software for parametric modeling. Ansys Workbench software was utilized to analyze the static characteristics under two distinct working conditions. Output included von Mises stress distribution clouds, displacement clouds, and contact stress distribution clouds between inner and outer rings. Findings indicated that under radial load alone, the inner ring experienced maximum von Mises stress on the loading surface, while the outer ring experienced maximum equivalent stress at its outer edge and maximum contact stress where the inner surface was squeezed. Combined loads resulted in higher stresses for both rings compared to radial load alone. Thermal coupling analysis was conducted to assess the impact of frictional heat during operation. Results revealed that rotation under radial load generated frictional heat between the inner and outer spherical surfaces, leading to temperature increase with rotation speed.
