The SHF-2A-GR high-accuracy harmonic-drive gear reducer features a large hollow shaft and can be incorporated into a custom housing to achieve an optimum package size. The design is both axially shorter and lower in weight, and uses the "S" tooth profile. Gear reduction ratios of 50:1 through 160:1 are available in a single stage. The large hollow shaft enables the user to pass shafting, wire bundles, or other components directly through the gearing's center.
