The CSF and CSG are Harmonic Drive's cup-type strain wave gear component sets (wave generator, flexspline, circular spline) that a robot builder integrates with their own motor and housing. The CSG-2A line covers ten sizes from 14 to 65 with ratios of 50:1 to 160:1, rated from 7 Nm to 1,236 Nm; it is the classic zero-backlash reducer in industrial and collaborative arm joints.

Editor's notes
Numeric attributes left unset because this is a series record (sizes 14–65, ratios 50–160); per-size figures are in the notes. Quotation only at Harmonic Drive LLC (direct) (https://www.harmonicdrive.net/products/component-sets/cup-type/csg-2a). Unverified (free text): csf-2a-per-size-specs. Attribute numbers are the smallest size (CSG-14-50-2A-R: 7 Nm rated, 23 Nm repeated peak, 0.09 kg) and gear_ratio 100 is one of the available ratios; the series spans up to 1,236 Nm rated / 3,419 Nm peak / 12 kg. Accuracy 1–1.5 arc-min. Series records do not fit single numeric attributes well; editor may prefer to drop the numbers.
