Fine Cyclo

For over 30 years, Sumitomo Drive Technologies has been providing reducers that excel in applications where you demand precise positioning and zero-backlash, such as robotics and automation.

Fine Cyclo® High Precision Gearboxes DA-Series


Angular contact ball bearings directly integrated in the gearbox housing.

Improved design providing very accurate motion quality and increased torque density and bearing capacity.

  • Highest torque density in a single stage unit
  • Ideal for robotic applications
  • Hollow shaft possible
  • Fully sealed modular version with motor adapter and clamp ring available

Fine Cyclo UA-Series


Spur gear pre-stage and three or four (UA115) eccentrics providing high transmission accuracy, minimum speed ripples and minimum vibration.

The new UA series offers improved performance in torque density, positioning accuracy, and movement accuracy. Additionally, the Fine Cycle UA series has improved output bearings and is highly efficient even at low speeds.

  • Less than 0.5 arcmin Lost Motion
  • Ideal for applications with traverse movements
  • Highest Torque density available on the market
  • Highest overall available Torque
  • High input and output speeds are possible
  • Additional ratios available on request

Variants:

  • Basic design to be fully integrated into robotic arms
  • Fully sealed version including motor flange available

Fine Cyclo A-Series FC Type


Reduction kit without output bearing.

Maximum freedom and flexibility for installation of external bearings and for integration in specific machine designs.

  • Less than 1 arcmin Lost Motion
  • Pre-filled with grease
  • Motor adapter on request
  • Zero backlash

Input Shaft Variants:

  • Keyway
  • Clamp Ring
  • Spline

Additional A-Series Options


Fine Cyclo C-Series
