Effect of loading capacity (pressure–velocity) to tribological properties of CuSn10 bearings

Bronze is widely used as a journal bearing material for copper-based alloys. These alloys ensure that journal bearings possess the expected properties. These materials that possess tribological properties give good results at journal bearings. In this study, friction and wear properties of journal bearings manufactured by CuSn10 bronze and the effect of p.v. (pressure–velocity) parameter have been examined and compared. SAE 1050 steel shaft has been used as counter abrader. Experiments have been carried out for p.v. values of 0.0125, 0.025 and 0.05 (N/mm s) and for every half an hour totalling to 2.5 h by using radial journal bearing wear test rig. As a result, depending on p.v. values, high friction coefficient and weight loss have been obtained under dry condition more than those obtained under lubricated condition.
