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