MASTER GEAR

A Master Gear is a highly accurate, certified reference gear used specifically for inspection and calibration of production gears. Its primary function is to serve as a standard against which working gears are checked, typically using a gear rolling tester. By meshing the Master Gear with a component gear, any errors in tooth thickness, pitch, profile, or runout of the component gear are revealed, ensuring the final product meets stringent quality and performance standards. They are manufactured to the highest precision grades and are essential for maintaining quality control in gear production.
