The aim of the work was the experimental and theoretical evaluation of the influence of the most important
parameters determining the holding torque of a thin-walled bearing shell inside a housing bore of a connecting
rod. The main investigated parameters were defined by authors experience in this field. In the first stage of
research, a special test stand was designed in order to allow measuring the real values of the friction torque for
different variants of bearing shell geometries and assembly conditions, additionally analysing the influence of
the locking lip. Subsequently, theoretical computer-assisted FEM simulations were performed.
