SEW-EURODRIVE R70-7.84-3540 Inline Helical Gearbox

SEW-EURODRIVE R70-7.84-3540 Inline Helical Gearbox is a compact foot-mounted reducer from SEW-EURODRIVE’s R70 family. It provides a 7.84:1 reduction and an output torque rating of 3,540 in-lb, enabling predictable speed reduction and torque multiplication in small drive trains. The inline configuration keeps input and output shafts on a straight axis, simplifying installation with standard mounting patterns and straightforward coupling to motors. As part of the R-series inline helical lineup, the R70 designation identifies its size class within the family, balancing compact dimensions with dependable load capability for light- to mid-duty applications. Helical gearing in this design delivers smooth torque transmission and relatively quiet operation, making it suitable for compact automation tasks where space is at a premium, consistent performance is required, and installation layouts favor an inline footprint. Engineers often reference the model identifier R70-7.84-3540 to confirm fit with drive trains and to ensure alignment with the system's torque and speed requirements.
