Lightweight Precision Harmonic Drive Gearheads

Ideally suited for robotic and machine tool applications, the new CSG-LW and CSF-LW Harmonic Drive™ gearheads are 30% lighter than previous designs without reducing the torque rating.  The CSG high-torque gearhead delivers 30% more torque and 40% longer life while maintaining zero-backlash, 1 arc-min accuracy, and ± 5 arc-sec repeatability.  A high capacity cross roller bearing and output flange is used to support the driven load.

A wide variety of sizes and reduction ratios are available with maximum peak torques ranging from 450 in-lb. to 60,500 in-lb.

Key features include:

  • Zero Backlash
  • High torque capacity
  • Accuracy <1 arc-min
  • High torsional stiffness
  • High efficiency
  • Smooth operation
  • Robust cross roller output bearing
  • Output flange for direct mounting of load

These models are ideally suited for the following applications-

  • Industrial Robots  -allowing operation with higher acceleration rates and payload capacity
  • Mobile Robots  -allowing lower weight designs which improves battery life with sacrificing performance
