Internal Gears Capabilities
•Pitch Diameters: 1/4″ to 48″
•Number of teeth: 4 teeth to 400 teeth
•Face Width: 9″ maximum face width
•Pitch Types: Diametral Pitch, Module Pitch, Circular Pitch, Agma Stub, Combo Stub, Nuttal Stub, Full Fillet and others.
··(Other less common pitch cutters can be rented or purchased as needed).
•Tooth size: 120 Diametrial Pitch to 2 Diametral Pitch, .2 Module to 12 Module, .05″ Circular Pitch to 3″ Circular Pitch.
•Pressure Angles: 14.5° PA, 20° PA, 25° PA, are the most common pressure angle gear tools that we stock.
··(Other less common, pressure angle gear tools are available to rent or purchase as needed.)
Materials: steels, hardened steels, pre-heattreat steels, stainless steels, cast iron, aluminums, delrin (aceytl), nylon, uhmw and other plastics, non-metallics (phenolics), brass and bronzes, graphite, titanium, monel, inconel. We can and have made internal gears out of many other materials as well.
Internal Helical Gears
Although we do not get much call for them, some of our machines that produce Internal gears will also manufacture Internal Helical Gears.

Depending upon the complexity of your samples, in many cases, there is no charge for reverse engineering.
