We developed a tailor-made coupling solution for the PremiumFlow series. Its basis was a standard ROTEX size 28 with split hubs, taper bore and feather keyway. This type allows for radial assembly and disassembly of the coupling with no need for shifting adjacent components. Thus, an option is provided for dismounting individual belt segments. Compared to the catalogue version we reduced the coupling hubs to the minimum length to keep the distance between the belt strap segments as small as possible. The result is a maximum belt strap surface optimizing the crop flow and creating the condition for a tight seal between the individual conveyor segments.
