    Small end bearings of heavily loaded two-stroke diesel engines or, in general, bearings with duty cycles combining non-reversing loads with limited angular or oscillation very often only function marginally satisfactorily and tend to cause many problems. In this paper an analysis of these problems is presented. Construction of journal paths as well as calculations, based on the mobility-whirl angle method, were carried out. The influence of design factors, such as number and position of oil grooves, bearing clearance etc., will be investigated and it will be shown that optimization of these parameters only results in marginal improvements. An impressive increase in minimum film thickness, however, can be obtained by pre-stressing the piston pin with regard to its bearing housing. Subsequently, a suggestion for a practical bearing configuration is presented. (A)
