E CYCLO – Elastic Cyclo Sumitomo Drive Technologies

E CYCLO or Elastic Cycloseries features high rigidity due to its internal roller bearings. This is significantly higher when compared to the competition. Therefore, the E CYCLO can achieve higher performance in a smaller design envelope and thus lower costs.

High precision shaft gear with output flange and high rigidity

CYCLO’s unique ‘gearless’ design is distinctly superior to common involute gear speed reducers, operating in compression rather than shear, resulting in:

  • Minimal vibration
  • 500% Momentary shock-load capacity
  • Low backlash and extended operational life
