The F series parallel shaft gear unit pairs a two- to four-stage helical gear arrangement with a standard IEC motor, delivering high torque in a compact inline footprint. It is the workhorse drive for belt conveyors, screw conveyors, mixers and fans where the ratio is too high for a single-stage unit but a right-angle output is not required.
With ratios from 3.81:1 up to 281:1 across two, three and four stages, and output torque up to 18,000 N·m, one frame family covers most medium-duty conveyor and mixer applications. Foot-mounted, flange-mounted and shaft-mounted versions share the same gear sets, so spare parts and replacement units stay interchangeable across a plant.
Every unit is sized against your duty cycle, driven load and service factor before the order is confirmed, and each assembly is run-tested before packing. Hollow output shafts with torque arm or shrink disc are available for direct shaft mounting without a coupling.
