Custom Manufactured Precision Bevel Gears

Reliance Gear manufactures custom precision bevel gears including spiral bevel, straight bevel, hypoid, zerol, and coniflex gears.
With decades of experience in gear cutting and the most precise manufacturing equipment on the market, we can produce gears to tight tolerances that meet all AGMA up to Class 15 specifications. Our equipment and technologies include the latest Gleason bevel gear production machinery and advanced AutoCAD, SolidWorks, and UTS Gear Analyzer software packages. Our direct link with Gleason Works ensures that our technicians are always trained and equipped with the latest gear manufacturing technology.
All our gears are measured with precision CMM equipment, verifying that all dimensional tolerances are to spec. Our CMM equipment can also be used to reverse engineer gears with unknown dimensions.
