Harmonic Drive CSG-2A Strain Wave Precision Reducer (Component Set)

Harmonic Drive is the inventor and global leader of strain wave (harmonic) gearing. The CSG-2A component set (wave generator, flexspline, circular spline) spans 10 sizes 14-65 with ratios 50-160: rated torque (L10) 7-1,236 N·m, repeated peak 23-3,419 N·m, momentary peak 46-6,175 N·m, standard accuracy 1 arcmin (1.5 for size 14), zero backlash and high torsional stiffness (K1 0.34-54 x10^4 N·m/rad) at only 0.09-6.7 kg - the go-to precision reducer for cobot, humanoid, semiconductor and optics joints.
