HarmonicDrive® Speed Reducer for Precision Control SHF Series Unit Type (Hollow structure unit, hollow structure lightweight unit)

Features

  • Large bore hollow structure
  • High moment capacity bearings available
  • Simple design
  • Backlash-free
  • New lightweight type (20% lighter than the standard type) NEW

The SHF series unit type features a large hollow structure only achieved with the HarmonicDrive®.
It lets you easily figure out wiring and air piping designs, complex drive shaft designs and other equipment design challenges.
It can be used to boost performance in a wide range of applications including certain industrial robots, glass delivery, semiconductor manufacturing systems, and metal-cutting machines.
In addition to the conventional standard products, the development of the lightweight type makes this series even more complete.
Its newly designed shape and use of lightweight material, makes it about 20% lighter. 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.
