Helical gear units / Helical gearmotors
More efficiency in every situation
In six single-stage and fourteen two-stage and three-stage
sizes, the helical gearmotors by SEW-EURODRIVE ensure an
optimum ratio between power and space requirements.
Your advantages
- High power density
- Long service life
- R37 ... R167 Reduced backlash option
- RM series, specially designed for agitating
applications
The tried and tested modular concept and our strict quality
criteria allow SEW-EURODRIVE to provide a diverse range of
torques and reduction ratios with incomparably finely tuned
gradings. With this exceptional diversity, SEW-EURODRIVE
sets new standards in the field of drive engineering.
Available versions
- Single-stage or multi-stage
- Foot-mounted or flange-mounted
- Foot-mounted and flange-mounted
- Flange-mounted with extended bearing hub

Our complete range of helical gearmotors provides
the optimum size and power solution for every
drive task. And for operators with a
“weight-watching” issue, our multi-stage gear
units provide something special: Thanks to their
die-cast aluminum design, the models R07, R17 and
R27 are three particularly efficient lightweights
– ideal as satellite drives and for use in light
machine constructions. Reduced backlash helical
gear units are also available for particularly
precise requirements.

RM gearmotors with extended output bearing hub are
a special type of helical gearmotor. They were
designed especially for agitating applications and
allow for high overhung and axial loads and
bending moments. The remaining data corresponds to
that of standard helical gearmotors.
