Properties comparison of rubber and three layer PTFE-NBR-bronze water lubricated bearings with lubricating grooves along entire bush circumference based on experimental tests

The work presents experimental research conducted on comparable sliding bearings with lubrication grooves along entire bush circumference, assessing them against a different, modern solution. Movement resistance, pressures in bearing interspace and shaft orbits were measured and analyzed. It was proved that classic bush geometry is not appropriate for hydrodynamic lubrication.
