Slone Gear is a full service, shop floor gear measurement enterprise offering everything from hand gages to fully automatic laser measurement systems. It is our mission to shift gear inspection closer to the manufacturing machine.




Our customers love what we do
In partnership with large automotive OEM’s, we have successfully conducted extensive testing on our new technology which is now running in regular operation at multiple companies and plants.
“I can’t say enough good things about Slone Gear International. Brian Slone and his team have been fully committed to providing the highest quality product along with the most exceptional service in the gear inspection industry; they have far exceeded my expectations and that of Ford Motor Company’s. The laser gear inspection machine they have provided to Ford Motor Company has proven to be an absolutely invaluable tool; it allows us to accurately inspect gear geometry in less than 6 seconds! Sincerely, thank you Slone Gear team for all that you have done.“

“Thank you for your help and the help of Slone Gear on the new EQUATOR™ machines. Your help on the new gear runout program to quickly sort parts was awesome. We were able to quickly check the parts on the EQUATOR™ rather than tying up our analytical gear checkers. Your machine and program saved our company both time and money.“
