The FKM lightweight rollers consist of a PU-coated fiberglass tube that is rotatably mounted on a fixed axle. The lightweight rollers are often used as idlers in horizontal storage systems of pickling lines in the steel industry, where they can play their advantages to the fullest. A low mass moment of inertia facilitates acceleration by the belt, minimizing wear on the coverings. The rolls can be installed more easily if the installation site is not accessible with a crane due to their low weight.
FKM lightweight rollers have been sold to customers in Germany for many years. Since 2020, sales to the US steel industry through FKM USA have shown encouraging growth as well. A special PU lining is used in the USA. In addition to high wear resistance, this material also resists temperatures of up to 130 °C.
