What The Adams Company does
The Adams Company is a precision gear, shaft, and custom power transmission component manufacturer headquartered at 8040 Chavenelle Rd, Dubuque, Iowa. Founded in 1883 originally as Roberts & Langworthy Iron Works, the firm pivoted from foundry and luxury automobile (Adams-Farwell) production into gear and shaft manufacturing in 1915, fully exiting foundry operations in 1975. Today it operates as a division of Vector Companies, a multi-brand platform formed in August 2024 alongside Atlas Gear Company and Atlas Global, with Northend Gear & Machine added in October 2025. The company employs 251-500 staff across 2nd and 3rd shifts and runs a comprehensive in-house capability stack spanning CNC gear hobbing (Mitsubishi, Pfauter, Barber Coleman), gear shaping (Mitsubishi ST-40, Fellows), ID/OD and bore grinding (Okamoto, Okuma, Mitsubishi), CNC thread grinding, 5-axis worm milling (Yama Seiki, Toyoda, Okuma), straight bevel gear cutting (Gleason 104/114/2A), broaching, and full ISO 9001 inspection with Gleason 3025 and Mitutoyo CMM systems.
The business model is print-to-spec custom contract manufacturing for enterprise OEMs, with quote-based pricing (no public pricing), regional field sales supplemented by inside sales and manufacturer's reps (e.g., Jorgensen Sales), and an industry trade-show-heavy customer acquisition motion (CONEXPO-CON/AGG, MINExpo, World of Asphalt, Motion + Power Technology Expo, International WorkBoat Show, AGMA Fall Technical Meeting). Target verticals include construction and heavy equipment OEMs (Caterpillar, John Deere, Komatsu, Volvo), mining and aggregates (Deister Machine, David Brown Santasalo, Flender, ESP), commercial marine, agricultural and forestry equipment, EV manufacturing, and general industrial OEM applications. Customer engagement is anchored by supplier qualification documentation, manufacturability feedback during quoting, and full inspection-backed quality records at every stage. The company also operates Gear School, an annual two-day hands-on training program for entry-level and early-career professionals, delivered in partnership with Helios Gear Products, Advanced Heat Treat Corporation, Kapp Niles, and Penta Gear Metrology.
