## Notes

Cup-type strain-wave (harmonic) gear reducer component used to build precision arm joints; no integrated motor, so motor/electrical/comms fields are null. Sizes 8/14/17/20/25/32/40/50 with reduction ratios 50/80/100/120/160:1. Rated output torque spans roughly 3.5 N·m (smallest size) up to about 196 N·m (larger sizes) with allowable peak torque above 2,300 N·m on large sizes, per distributor listings; specific per-size/ratio values are not confirmed from a primary Leaderdrive datasheet, so left null. Marketed zero-backlash (recorded 0). Quote-only pricing.
