CSF-14-50-2UH

Name: Harmonic Drive CSF-14-50-2UH
Brand: Harmonic Drive

An exact size-and-ratio gear-unit record. Published torque and stiffness values remain rating-table claims, not an RCI robot-joint duty-cycle, thermal, life or backlash test.

Architecture

Housed CSF-series strain-wave gear unit with integrated output bearing, size 14 and 50:1 nominal ratio

Identity

Harmonic Drive CSF-14-50-2UH · Also: CSF-2UH size 14 ratio 50, CSF-14-50-2UH gear unit
