Sumitomo Product Lines we Provide:

FINE CYCLO High Precision Gearboxes

FINE CYCLO® reducers excel in applications where you demand precise positioning, such as robotics and automation; and feature:

  • Zero backlash
  • Minimal lost motion
  • High-torsional stiffness

E CYCLO Elastic CycloShaft Gear Units

High precision shaft gear with output flange and high rigidity

The new E CYCLO series 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 Rigidity
  • Lost Motion 1.0 arcmin
  • Transmission error 0.75 arcmin
  • Maximum drive speed up to 8500 rpm
  • Permissible torques up to 284 Nm
  • Radial loads up to 2050 N
  • Axial loads up to 3000 N
  • Completely sealed including cross roller main bearing

Cyclo Drive for Servo Motors

Reducer featuring high strength and reliability, thanks to its unique Cyclo® mechanism

  • Cyclo® reducer with a flange, for servo motors.
  • Utilizes unique Cyclo® mechanism for durability and long product life

Two Series:

  • Standard-Backlash Series
  • Low-Backlash Series: 6 arc min (12 arc min for reduction ratio 6)

Servo Hyponic

Requires no oil changes and up to 93% efficient. 

  • Maintenance-free grease lubrication eliminates oil changes
  • A wide range of choices (up to 13,100 N·m) to accommodate all types of uses.
  • Modular design allows for multiple gearheads and motor combinations for increased service factor.
  • A variety of industry packages and options are available, including grease lubrication, antibacterial coating, waterproofing, and low-temperature requirements.
