FEX Extruder Gearboxes – Single-screw Extruders

The flat extruder gearbox of the FEX Series has been specially developed for the extrusion process in the plastics industry and for recycling plants with a view to the axial loads that occur. The gearbox – available in Z or U shape – is characterized by its high power density and compact design.

The sizes range from a centre distance of 125 to 630 mm and have been dimensioned based on the respective screw diameters. The torques of these models lie in a range of up to 200,000 Nm with freely selectable gear ratios.

A Variety of Options for Every Application

A wide variety of options is available for the FEX extruder gearboxes. Whether motor flange, coupling, or oil/water cooler – the gearboxes are ideally adapted to your application. They come complete with a thrust bearing (self-aligning roller thrust bearing) specially designed for the purpose. Screw pull-out to the front or to the rear is also individually implementable.
