U slučaju abrazivnih i korozivnih primjena, normalno je da će se u određenim komponentama dogoditi snažnije trošenje. S obzirom na gornju primjenu trošenje se može odvijati uglavnom u radnom kolu, miješalici, usisnoj ploči, rukavcu osovine, uljnom prstenu, mehaničkoj brtvi, kućištu pumpe, cjedilu, kućištu motora i ispusnoj spojki. Ovisno o radnim uvjetima vijek trajanja tih dijelova može značajno varirati i može biti kraći od pravnog zakonskog razdoblja.
