In modern mechanical engineering and metallurgy, journal bearings are an integral part of rotating equipment such as turbines, generators, pumps, and other systems operating under high loads and high rotational speeds. The reliability of these bearings is a critical factor, as their failure can lead to significant economic losses due to unplanned equipment downtime. Research is aimed at improving the efficiency, durability, and wear resistance of journal bearings. Numerical analysis methods, such as the finite element method (FEM), play an important role by allowing the simulation of bearing behaviour under load and temperature conditions. Additionally, experimental tests have demonstrated the effectiveness of using polymer coatings and low-viscosity lubricants to enhance the performance of bearings. Optimizing the design of bearings improves their stability and reduces vibration when operating under challenging conditions.
