Custom Gear Manufacturers

Custom gears supplier for OEMs

AmTech 25+ years of custom gear manufacturing services are well suited for high quality gears, related components and transmission gear assemblies on mid-to-high volume parts per customer specifications. All products are manufactured with the latest machinery capabilities with an emphasis on cost effective production. Our wide variety of custom gears includes: ring & pinion gearsets, worm / helical / planetary gears & gearboxes. Primary clients for AmTech gear technology are in the Automotive, Agricultural, Off-Highway, Machinery, Pump and climate control OEM / Tier 1 / Tier 2 manufacturing segments.

The high quality materials we use include carbon steel, stainless steel, bronze and plastics. We can also finish and heat treat parts, and offer just-in-time delivery services when required.

Common base materials for our gear products are steel, stainless steel, iron, bronze and composites which are converted into the final product by CNC turning, gear forging, conventional & non-circular grinding, hobbing, skiving, shaving, shaping, milling, honing, broaching with subsequent heat treatment & finishing. Whether your product is a new design, experiencing engineering / design changes or an existing production component – AmTech has the experience to support your project needs. 

Non-Ivolute Custom Gear manufacturerGear Cutting

To precisely cut gear teeth, we fully equipped with top of the line Gleason Phoenix CNC tooth cutting machines. Also, we have Gleason Phoenix and Lorenz systems Machines for gear hobbing and gear shaping.

Gear Grinding

Precision tooth grinding of custom gears will result in parts that operate quietly and wear evenly (an OEM production note for high speed gear boxes and automotive applications). Our custom transmission gear tooth grinding capabilities include high production line capacity with the expertise of holding very tight tolerances. This accuracy of within 20 millionths of an inch, or one half of a micrometer are efficiently monitored with these cutting edge machines.
