Reliable transmission of drive torque

Offset gear motors

Full drive performance, also in a small space

Our offset gear motors are specially designed for space-saving drive solutions. The housing design offers good ground clearance for travel applications at ground level. The large center distance between the parallel gearbox shafts enable these units to be used in a central drive arrangement, e.g. when fitted with shaft ends on both sides. What else do they offer?

  • Wide range of gear ratios
  • Cost-effective solutions with high efficiency
  • Practical designs for a variety of travel applications
  • 9 gearbox sizes
