Experimental research on water-lubricated marine stern tube bearings in conditions of improper lubrication and cooling causing rapid bush wear

The conducted research determined that certain bearings continue to work properly despite a lack of lubricant flow and cooling. This is due to low frictional resistance levels, resulting in sufficiently low heat being generated in the friction zone of such bearings and dispersed into the surroundings once the bearing׳s temperature has risen and stabilized at a safe level.
