Harmonic Drive CSF and CSG Housed Gear Units
Harmonic Drive CSF and CSG Housed Gear Units
Harmonic Drive CSF-2UH and CSG-2UH combine cup-type strain-wave gearing, a housed mechanical assembly and a cross-roller output bearing with flange. CSF is the standard-torque choice and CSG the higher-torque choice; LW versions reduce unit mass in selected configurations. These are externally driven gear units, with a supplied output support arrangement that distinguishes them from bare 2A component sets.
Review Summary
Consider the 2UH families when an OEM wants zero-backlash reduction and an integrated output-bearing structure without designing a complete component-set housing. Choose CSF or CSG by matched torque-duty data, then compare standard and LW bearing stiffness as well as weight. The motor, drive, holding strategy and machine safety remain separate parts of the finished axis.
