Since 1973, Carnes-Miller Gear has been at the forefront of precision gear manufacturing, evolving from a specialized gear shaping and hobbing operation into a comprehensive full-service job shop. Operating from our dedicated 18,000-square-foot facility in Locust, NC, our team has navigated five decades of industry challenges while consistently delivering superior planetary gear sets and epicyclic gearing systems. We've built our reputation on extensive training in gear tooling, equipment, nomenclature, and tolerancing, enabling us to serve demanding sectors including aerospace, defense, medical, industrial, mining, transportation, construction, agricultural, and rail industries. Our commitment to reliability, expertise, and quality has made us a trusted partner for OEM manufacturers and aftermarket suppliers requiring precision planetary gear solutions. We maintain competitive pricing while investing in cutting-edge technology and maintaining the highest quality infrastructure, ensuring every planetary gear set meets or exceeds AGMA standards and customer specifications.
A planetary gear set, also called an epicyclic gear system, consists of a central sun gear, multiple planet gears that rotate around it, and an outer ring gear. The planet gears mesh with both the sun gear and ring gear simultaneously. This configuration provides high torque density, multiple speed ratios, and compact packaging, making planetary gear sets ideal for applications requiring efficient power transmission in limited space.
