Our complete range of helical gearmotors provides the optimum size and power solution for every drive task. And for applications where weight is an 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.
