The competitive environment forces producers in agricultural machine industry to decrease the costs. Producers as well as sub-suppliers need to find possible savings. The paper presents results of laboratory experiments with real journal bearings made of bimetallic alloy performed to find out possible replacement of a rolling bearing by a journal bearing. An important correlation between the results of laboratory experiments with a model of tribological system and the real journal node can be achieved by a maximum approach of simulation features by real running conditions. Thus, the given experiment conditions result from the chosen application, i.e. a steering servo unit in mobile machines. The experiments were performed on the Tribotestor M'06'' testing machine.Keywords:
