These custom precision helical gears are manufactured from 42CrMo alloy steel, a material prized for its excellent hardenability, impact strength, and wear resistance. They are ideally suited for high-speed, heavy-load power transmission applications, capable of withstanding continuous alternating loads without tooth breakage or deformation. Two surface finish options are available: black oxide coating (providing rust protection for humid environments) or an untreated raw finish (facilitating subsequent heat treatments such as quenching or carburizing). We offer professional OEM customization, adjusting parameters—such as module, helix angle, tooth count, face width, and bore specifications—based on customer drawings to suit gearboxes, transmission mechanisms, and automated powertrains. As high-quality OEM helical gears, they feature strictly controlled tolerances for tooth profiles and bore fits, ensuring smooth meshing and reduced transmission noise. Balancing toughness and strength, these 42CrMo helical gears are an excellent choice for heavy-duty transmission systems.
