    • The tried and tested modular concept and our strict quality criteria allow SEW-EURODRIVE to provide a diverse range of torques and gear 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
RX series (single-stage)

For high output speeds, the exclusively single-stage gear units RX57 to RX107 offer compact solutions for your system design.
Technical data
Gear unit gear ratio [i] 1.30 to 8.65
Output torque [Nm] 36 to 830
Motor power range [kW] 0.12 to 45
R series (two-stage and three-stage)

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.
Technical data
Gear unit reduction ratio [i] 3.21 to 289.74
Multi-stage gear unit reduction ratio [i] 90 to 27,001
Output torque [Nm] 31 to 18,000
Motor power range [kW] 0.09 to 160
RM series

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.
Technical data
Gear unit reduction ratio [i] 4.29 to 289.74
Multi-stage gear unit reduction ratio [i] 134 to 27,001
Output torque [Nm] 270 to 18,000
Motor power range [kW] 0.12 to 160
