Ultra-lightweight Gearhead from Harmonic Drive

Harmonic Drive LLC

Ultra-Lightweight Gear Units from Harmonic Drive LLC

New gear units boast ultra-thin profile and extreme lightweight.

Harmonic Drive LLC, a leader in high precision motion control introduces two new ultra-lightweight gearheads. The two models, 8 and 11, are the smallest and the first to be released in the CSF-ULW series. 

This series features a newly engineered lightweight structure with an ultra-compact shape. The ULW line maintains the same performance standards as the CSF-2UH series. Ideal for use on end of arm axes for small industrial and collaborative robots, the CSF-ULW is also well suited for general industrial machinery where weight is a critical factor. CSF-ULW gears are available with 3 reduction ratios; 30:1, 50:1 and 100:1.

CSF-2UH-ULW: 

  • Zero backlash
  • High accuracy
  • Ultra-lightweight
  • Super flat configuration, 19mm (size 8); 21.5mm (size 11)
  • Outer diameter: φ 42.5mm (size 8); 50.5mm (size 11)
  • Reduction Ratios 30:1~100:1
