Analysis of chemical resistance
;If castors and sulu:link href="dc7cb284-4cdd-4b61-b17c-46b947d79ac8" provider="page" target="_self" title="Wheel solutions">wheels are likely to come into contact with aggressive substances, their chemical resistance must be taken into account when selecting the right products. The better we know the environmental conditions under which castors or wheels are to be used, the more precisely we can determine which product will be most suitable. This could prevent premature castor failure due to corrosion, surface changes, embrittlement, loss of strength, or lubricant leakage. Careful coordination of all components guarantees the maximum service life.
