HarmonicDrive® Speed Reducer for Precision Control CSF Series Unit Type (Standard structure unit, standard structure lightweight unit)

Features

  • High stiffness bearings
  • Simple design
  • Backlash-free
  • High efficiency
  • High rotational accuracy
  • New lightweight type (30% lighter than the standard type) NEW

The HarmonicDrive® unit type is the high-performance speed reducer outfitted with high stiffness bearings (cross roller bearings).
It saves on space and is cost efficient.
In addition to the conventional standard products, the development of the lightweight type makes the CSF series even more complete.
With a newly designed shape and its use of lightweight material, it's about 30% lighter than the standard products. The CSF series without question makes machinery and equipment lighter. Because of its light weight, when it's used with industrial robots, it will make them faster and grants them greater load capacity.
