In close cooperation with an internationally leading manufacturer of highly automated production lines for the automotive, rail and aircraft production, RINGFEDER® has implemented a tailor-made special solution: In a modular conveyor system, which feeds car body sheets to several forming plants, specially designed steel disc couplings of the RINGFEDER® TND series serve as torsionally rigid connection elements between between the drive and the roller conveyors as well as between the conveyors themselves – as up to six roller conveyors are provided with just one single drive. The individually designed shaft connectors meet the exceptionally high customer requirements with regard to compactness, the ability of compensating for misalignments, corrosion protection, and transmissible torque, and are furthermore extremely installation- and maintenance-friendly.
