This paper presents a comprehensive study of the thermo-mechanical behavior of a short hybrid (hydrostatic and hydrodynamic) journal bearing using the Finite Element Method (FEM). The dimensions and operating conditions are similar to the cage-ring contact occurring in a rolling element bearing. This study focuses on understanding the performance and characteristics of the bearing under varying supply pressures and temperatures. The FEM approach is employed to simulate the mechanical and thermal behavior within the bearing. The results demonstrate that a higher supply pressure significantly increases the load-carrying capacity. However, this is accompanied by a rise in shearing losses. Additionally, an increase of supply temperature reduces power losses.
