Harmonic Drive CSF-GH and CSG-GH Servo-Mount Gearheads
Harmonic Drive CSF-GH and CSG-GH Servo-Mount Gearheads
CSF-GH and CSG-GH are servo-mount strain-wave gearheads with a cross-roller output bearing and Quick Connect motor coupling. CSF supplies the standard-torque choice, while CSG raises the torque ratings in matched frames. Both rely on an external servo motor and drive, with the actual adapter and output arrangement selected for the application.
Review Summary
Consider GH when a directly mounted servo motor, supported output and compact high reduction fit the machine layout. Compare CSF and CSG using the same size, ratio and duty basis. The coupling simplifies attachment, but the shaft dimensions, motor interface and tightening procedure must still match the exact supplied gearhead.
