PRELIMINARY - PRODUCT/GEOMETRY CANDIDATE ONLY - NOT APPROVED FOR PROCUREMENT, FABRICATION, ASSEMBLY, POWERED TESTING, MOTION, OR ENERGIZATION

Ten reduced leg axes now point to four physical belt modules.

Purchasable MISUMI P-bore-plus-tap pulley and belt candidates replace ratio-only transmission placeholders. The knees now use their own 16:40, 2.5:1 XH540 module so the static screen can fit below the connector-current boundary.

What this closes—and what it does not

The ratio, tooth counts, product families, nominal widths, belt lengths and center distances are coherent candidates. Nominal horn/stub/shaft adapter geometry now exists separately. The knee change is an architecture correction, not continuous-torque proof. No torque-capacity, tooth-load, belt-tension, fit, fastener, guarding, alignment, thermal, fatigue or physical validation credit follows. Product availability and written quotations must be reconfirmed before procurement.
