Primary Industries in Peoria

Peoria’s strongest manufacturing sectors — and the precision parts we machine for each.

Industrial Equipment

OEM replacement & custom components

Peoria is synonymous with heavy equipment manufacturing thanks to Caterpillar Inc.'s global headquarters. Cat's massive operations drive demand for hydraulic pumps, valves, cylinders, power-transmission components, and material-handling systems across Central Illinois. Komatsu and other heavy equipment companies maintain regional presence. Keystone Steel & Wire in nearby Bartonville produces industrial wire and fencing products, and the Illinois River corridor's grain processing and ethanol plants add demand for conveyors, pumps, and heat exchangers.

Robotics & Automation

Custom brackets, housings & fixtures

Peoria is the global headquarters of Caterpillar, which has deployed hundreds of autonomous haul trucks in mines worldwide and continues to expand its autonomous construction equipment line. Cat's Peoria R&D campus develops the autonomous driving systems, perception stacks, and robotic assembly processes used across its product range. The region's manufacturing base — including Komatsu operations and dozens of Cat suppliers — increasingly adopts robotic welding and machine-tending to support heavy-equipment production.

Defense

Mil-spec components & assemblies

Peoria's defense contribution leverages Caterpillar's manufacturing DNA — the city's machining expertise in heavy vehicle drivetrain, hydraulic, and structural components translates directly to Army and Marine Corps ground vehicle programs. BAE Systems and Oshkosh Defense source from the central Illinois supply chain.
