Purpose. One should clarify the issues concerning the wear reduction of details of freight car side bearers, costs reduction for the worn details reconstruction, improvement the dynamic characteristics of railway vehicles and the increase of their movement safety. Methodology. Wear-resistant elements of the side bearers are made in the form of removable metal-ceramic plates, entrenched on friction planes. Findings. During operation due to pollution, wear of friction surfaces and other causes the power characteristics of side bearer may significantly vary, which adversely affects the dynamic qualities of bogies, and as a result the train traffic safety. Therefore, the solution proposed by the authors concerning the operation improvement of elastic frictional side bearers by means of their modernization is an urgent one. Originality. The design of the bogie side bearer of freight car was improved. Friction wedge was set on the spring; its inclined surface interacts with a support inclined platform of a plate through the plate with the durable elements in the form of metal-ceramic inserts. Practical value. The use of wear-resistant elements in the form of interchangeable metal-ceramic inserts will reduce the wear of connection joints of bogie and a freight car frame, improve its dynamic qualities. It will also decrease the costs for restoration of worn side bearers by friction.
