In the agro-complex, as well as in other sectors, the use of polymeric materials is one possible way forward in the innovation and development of machines and their parts. However, machine products place high demands on the materials from which they are made. Polymeric materials are currently able to compete in certain areas where metallic material would traditionally be used; however, one of their limiting characteristic is their ability to withstand elevated temperatures. This paper describes the hardness of polymeric materials when influenced by heat, generated during the double body abrasion. The paper also describes the abrasive wear of both polymers and polymeric composite systems, as well as cast iron, used in agricultural production. Heat intensity during the two-body abrasion results in a 28% fall of the composite systems hardness, to 18% fall of the Polyamid 6 hardness and to 13% fall of the Murtfeld hardness.Keywords:
