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 bearings in Pennsylvania”
2“Who supplies precision angular contact ball bearings in Pennsylvania”
3“I need a Pennsylvania bearing supplier for a long-run high-speed conveyor line upgrade, who should I talk to”
4“Top industrial bearings suppliers in Pennsylvania for OEM machinery buyers”
5“Which Pennsylvania industrial bearing suppliers can handle aerospace-grade bearings with full traceability and certification”
6“List 20 industrial bearings 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.
