37 more companies were named at least once. Companies outside the top ten are counted in the averages but not named here.

Also named, based in another state

AI assistants named these companies too, but MacRAE'S lists them in a different state, not Illinois. 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. 1“Best suppliers of industrial bearings in Illinois”
  2. 2“Who supplies precision angular contact ball bearings in Illinois”
  3. 3“I need a Illinois bearing supplier for a long-run high-speed conveyor line upgrade, who should I talk to”
  4. 4“Top industrial bearings suppliers in Illinois for OEM machinery buyers”
  5. 5“Which Illinois industrial bearing suppliers can handle aerospace-grade bearings with full traceability and certification”
  6. 6“List 20 industrial bearings 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.
