Gear Services

Prototypes, Short-Runs & Reverse Engineering

Because of our broad capabilities, Geartronics produces complex gears that would require some gear manufacturers to use outside sources. Our talented milling and turning professionals complement our gear cutting experts ensuring all your critical dimensions and finish requirements are achieved.

Our experienced staff will work with you to meet your requirements for prototype and short-run custom, engineered gear solutions. And if the need arises, we’ll work with you to reverse engineer a solution for an existing gear or gear assembly. With our diverse manufacturing capabilities, we will strive to meet your requirements for custom gears, racks, worms, shafts, splines, assemblies and other critical components.

When required, all orders will be accompanied by a F.A.I. and C. of C. Manufacturing records are kept in house along with material samples for ten years.
