Also named, based in another state

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 power transmission components in Illinois”
2“Who supplies taper-lock bushings for power transmission in Illinois”
3“I need a Illinois power transmission partner for a new conveyor line build-out, who should I talk to”
4“Top power transmission components suppliers in Illinois for OEM machinery buyers”
5“Which Illinois power transmission component suppliers can assist with sizing and selecting shaft couplings and bushings for high-torque applications”
6“List 20 power transmission components 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.
