Double Helical Gear Manufacturers Industry Leaders

Carnes-Miller Gear achieves AGMA 10 quality ratings on shaped and hobbed gears, and AGMA 13 on ground gears. The AGMA 13 rating represents a high level of precision and is validated through in-house nital-etch testing and Gear Charts, ensuring consistency and accuracy across every manufactured component.

Carnes-Miller Gear offers external gear grinding up to 400mm (15.75 inches) in diameter. For cut teeth only services using shaping or hobbing, capacity extends up to 200mm in pitch diameter. Helical gear face lengths can be manufactured up to 300mm, with helix angles accommodated up to +/- 45 degrees.

Double helical gears are widely used in aerospace, defense, mining, industrial machinery, transportation, rail, construction, agricultural equipment, and medical devices. Their ability to handle high loads without generating axial thrust makes them especially valuable in power transmission systems that require reliable, long-term performance in challenging environments.

Yes. Carnes-Miller Gear offers comprehensive reverse engineering services for obsolete or discontinued gear components. Their team uses dimensional data collection and process planning to recreate gears to original or improved specifications, providing a reliable source for aftermarket replacement parts across industrial, mining, rail, and specialized equipment sectors.

Turn-key gear manufacturing means Carnes-Miller Gear handles the entire production process in-house — from machining the gear blank and shaft to finished gear production complete to customer drawings and specifications. This approach provides tighter quality control, competitive pricing, and faster delivery compared to outsourcing individual manufacturing steps to multiple suppliers.

Yes. Carnes-Miller Gear provides custom gear modifications including lead modification, profile modification, and tip relief adjustments per customer specifications. All modifications are validated through Gear Charts to ensure dimensional accuracy. These services support specialized performance requirements in aerospace, defense, medical, and high-end industrial testing applications.
