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 reduction ratio [i] 1.30 … 8.65
Output torque [Nm] ([in-lb]) 36 … 830 (320 … 7350)
Motor power range [kW] ([hp]) 0.12 … 45 (0.16 … 60)


R Series (two- and three-stage)

The complete program of helical gear motors 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 have a particularly special solution. Thanks to their die-cast aluminum design, the models R07, R17 and R27 are 3 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 … 289.74
Multi-stage gear unit reduction ratio [i] 90 … 27001
Output torque [Nm] ([in-lb]) 31 … 18000 (270 … 159310)
Motor power range [kW] ([hp]) 0.09 … 160 (0.1 … 215)



RM series

RM gearmotors with extended output bearing hub are a special type of helical gear unit. 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 gear motors.

Technical data
Gear unit reduction ratio [i] 4.29 … 289.74
Multi-stage gear unit reduction ratio [i] 134 … 27001
Output torque [Nm] ([in-lb]) 270 … 18000 (2390 … 159310)
Motor power range [kW] ([hp]) 0.12 … 160 (0.16 … 214.56)
