Also named, based in another state

AI assistants named these companies too, but MacRAE'S lists them in a different state, not Pennsylvania. They belong to that state's ranking, not this one.

The five questions we asked

Every company in this cell is measured on the same questions, written the way a buyer would type them. That is what makes the ranking a comparison rather than a collection of anecdotes.

1“Best suppliers of industrial gears in Pennsylvania”
2“Who supplies precision ground helical gears in Pennsylvania”
3“I need a Pennsylvania gear manufacturer for a custom low-backlash gearbox project, who should I talk to”
4“Top industrial gears suppliers in Pennsylvania for OEM machinery buyers”
5“Which Pennsylvania gear manufacturers can handle carburized and ground gears to AGMA 10 or better”
6“List 20 industrial gears companies in Pennsylvania with their specialties.”the roster question

Each question is asked more than once, which is why a company's score is out of 15 answers rather than out of the number of questions.
