Large gears show up in some of the worst physical places. Extra large gears are essential to mix concrete, dig tunnels, adjust cone crushers, and adjust turntables.

For over 60 years, we’ve been custom manufacturing large gears for customers across many industries – from mining to batch processing. Whatever your needs or application, Cogmatic’s Flame Machining Technology will custom build a gear that helps you get the job done and done right.
