About this product

LCSG-17-XXX-C-I is the manufacturer-drawn frame-17 LCSG-I high-torque cup-shaped strain-wave reducer. It uses a direct keyed input connection. The printed XXX is a reduction-ratio placeholder; the manual lists 50:1, 80:1, 100:1, 120:1 for this frame, recorded as configurations rather than separate products. Specifications retain the form-specific hosted manual values. The current series webpage publishes different ratings without identifying the applicable generation; those claims are documented as unresolved source differences and must not be substituted into this manual-defined product. The cover is the manufacturer family photograph showing several size examples, not one purchased assembly. Cover image: Manufacturer series image; size may vary. An exact-model announcement, launch or shipping date has not been verified.
