Application library
Ten mechanisms, each written as a load model with the arithmetic shown. Every worked example is computed from stated assumptions and screened against the reviewed catalog. Where nothing published fits, the page says so.

Of the 32 published configurations, 29 can deliver more torque at a hard stall than the gearhead is rated to carry.
The worst is MM-C1226-S01002-120A at 8.0 times its rating. Four sit at or below it. This one fact decides more of the pages below than any torque or speed requirement does, which is why every application page works the abnormal condition rather than leaving it to a footnote.
Medical and laboratory equipment
In medical and laboratory equipment the drive is almost never working hard. It is working quietly, intermittently, for a decade, inside a program that has to document why it will keep working. The engineering problem is that none of the specifications that get compared describe that: continuous torque is barely used, rated life in hours is barely accumulated, and the numbers that decide the outcome are the stall torque into an occlusion, the mesh order that reaches a technologist's ear, the reversal error at the start of an aspirate, and the count of starts rather than the count of hours.
Industrial instrumentation and automation
In instrumentation and automation the drive is small, the envelope is fixed before the motion is designed, and the mechanism is usually asked for a peak it visits constantly and a stall it visits by design. The engineering problem is that peak torque, lost motion and the end-stop condition are decided by three different numbers, none of which is the continuous rating that catalogs are sorted by. A gripper stalls on every cycle. A valve stalls at every close. An inspection turret is specified in arcseconds against a train with degrees of backlash.
Obsolescence, second source, and reshoring
Obsolescence is a condition, not an industry. The mechanism already exists, the volume is known, the price is known, and something outside engineering has forced a change: a part went end-of-life, a supplier's quality moved, a minimum order or a lead time stopped working, a cost target landed, or domestic content became a requirement. The engineering problem is to change the drive without reopening the qualification of everything around it, which means knowing exactly which properties of the incumbent the mechanism actually depends on.
None of these pages ends in a part number you have to trust.
Each one ends in a measurement you can take. If your mechanism is not on the list, the load model probably still is.
