Features

SHD series unit type Harmonic Drive®, which inherits the excellent performance characteristics of the SHF Series, weight and configuration compactness, and comprised of a cross roller bearing of high moment stiffness has been taken to new level.
SHD series unit type Harmonic Drive® are offered in a series of six different sizes, opening up new possibilities motion control speed reducers.

• Thickness has been reduced to 1/2 that of the SHF series
• Torque capacity is 70% of the SHF series
• Torsional rigidity is 80 to 90% of SHF series
• Hollow-Shaft construction
• Comprised in Cross Roller Bearing of High moment stiffness
