Large Gear

Our Core Competency is the passion for manufacturing large precision gears for any industrial application.

Brevini Gear Systems facility is able to manufacture and heat treat large-diameter, high-precision gearing.  We have state of the art equipment for gear shaping, grinding, heat treatment as well as measurement and inspection, so it’s natural that our forte is large, high-precision gear sets. Likewise, we have one of the largest test stands in the US, rated at over 6 megawatts: we definitely have the capability of testing large gearboxes.


  • Large, high-precision Internal Ring Gears
  • Planet and Helical Gears, Sun Pinions, Large Gear shafts
