Pokud je pravděpodobné, že kolečka nebo kola přijdou do styku s agresivními látkami, musí se při výběru správného výrobku brát v úvahu jejich chemická odolnost.
Analýza chemické odolnosti
Pokud kola přijdou do kontaktu s agresivními látkami, je třeba při výběru správných výrobků brát v úvahu jejich chemickou odolnost. Čím lépe známe podmínky prostředí, za kterých se kola nebo kolečka budou používat, tím přesněji určíme, který výrobek bude nejvhodnější. Tím lze předejít předčasnému selhání kolečka kvůli korozi, změnám povrchu, křehnutí, ztrátě síly nebo úniku maziva. Důkladná koordinace všech součástí zaručuje maximální životnost.
