Reducer lubrication and life testing

Lubrication, endurance testing, backlash verification, and life testing needed to qualify a precision robot joint reducer. Hard-to-develop (per ADR-0005): qualifying low-cost reducers for industrial duty-cycle life requires long-running endurance test fixtures, statistically valid sample sizes, and tight backlash-growth criteria — a manufacturing-process capability with low yield and slow feedback that distinguishes incumbents from new domestic suppliers.
